mx51 and mx53 are device tree only platforms, so we no longer need all these calls to clk_register_clkdev(). Only keep cpu0 and gpc_dvfs clk_register_clkdev() calls. Tested on imx51-babbage and imx53-qsb boards. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Add standby mode support for suspend, to enter standby mode: echo standby > /sys/power/state; Use UART or RTC alarm to wake up system, when system enters standby mode, SOC will enter STOP mode with ARM core kept power on and 24M XTAL on.

According to hardware design, mem bit must be clear before entering DSM mode, as ARM core will be power gated in DSM mode. Signed-off-by: Anson Huang <b20788@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Instead of using enum for clock ID, let's switch imx6qdl clock driver to use macro. In this case, device tree can reuse these macros to improve readability. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Add suspend support for i.MX6SX. To enter suspend, echo mem > /sys/power/state. To exit suspend, using RTC alarm or enable debug UART wakeup. Signed-off-by: Anson Huang <b20788@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

The board has no insufficient support to be fully functional and seems has no users. This patch removes support for this board. However, the support may be added in the future by using the devicetree. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

This patch adds a reset fallback if base address of watchdog is not set. This is intended for a targets not compatible with imx-21 watchdog, i.MX1 for example. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

This patch simplifies handling watchdog clock a bit. As an additional change, now we properly check WDT clock in a reset function. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

This patch separates DT and non-DT clock initialization procedure, so we can avoid a lot of unneeded clk_register_clkdev() for DT case. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Base address for driver is global, there are no need to use intermediate variable for it. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Use of_clk_get_by_name() for timer clocks for DT case. This patch eliminates a lot of unneeded clk_register_clkdev() calls for GPT. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

CONFIG_FHANDLE=y is needed when running systemd with version >=210, so that it can spawn a serial tty via getty. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Now all the macros in mx51.h and mx53.h are used nowhere, so remove them. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

The mx51_display_revision() is a dead declaration. Remove it. Also, move mx51_revision() into common.h. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

The only code left in mm-imx5.c is to create static mapping. While all IMX platform code are moved to use dynamic mapping, the file can just be removed now. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
-
Shawn Guo authored
These imx5 init_early[late] hooks are called only from mach-imx5x.c. Let's move them into mach-imx5x.c. While at it, replace the static mapping in imx51_ipu_mipi_setup() with dynamic mapping. Also this function and imx_src_init() do not necessarily to be called at .init_early hook, so move them into .init_machine. The mxc_iomux_v3_init() is dropped from imx51_init_early() in the moving, since it's only needed by non-DT boot. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

The imx5 pm code uses static mapping to access Cortex and GPC registers. The patch create struct imx5_pm_data to encode physical address of Cortex and GPC block, and create dynamic mapping for them at run-time. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
-

The imx5 pm code needs to access CCM registers. Let's remove the use of CCM static mapping in pm code by reusing the dynamic mapping created in clock code. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
-
Shawn Guo authored
Replace the static mapping of DPLL block with dynamic mapping by calling ioremap(). Ideally, this should be done by calling of_iomap(), so that the physical address of DPLL can also be retrieved from device tree. But unfortunately, DPLL blocks are not defined in DT in the first place. So to maintain the compatibility of existing DTB, we use ioremap() with physical address defines in the code.

Replace the static mapping of CCM block with dynamic mapping and retrieve CCM base address from device tree. Though it's not nice to encode the variable ccm_base in macros, it helps to avoid a massive churn on the code. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Most of the macros in crm-regs-imx5.h are used nowhere. Let's move the needed ones into the C files, and remove the header. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Instead of using static define and mapping, the patch changes imx5 code that reads chip revision from IIM to retrieve base address from device tree and use dynamic mapping. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Since i.MX51 supports DT only, it's more appropriate to call mxc_timer_init_dt() than mxc_timer_init() to initialize timer. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

The function imx51_soc_init() was used by non-DT boot only. Since i.MX51 supports DT only, the function can be removed now. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

After i.MX51 supports DT only, tzic_init_irq() can figure out the tzic_base on its own. Thus, it can directly be .init_irq hook, and mx51[53]_init_irq() can be saved. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
-
Shawn Guo authored
The function mx5_clocks_common_init() was created with a number of arguments to pass oscillator clock rate in non-DT boot. Since i.MX5 is DT only platform, the arguments can be dropped, and the clock rate can just be retrieved from device tree. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
-
Shawn Guo authored
Since i.MX51 becomes a DT only platform, we can make mx51_clocks_init() a DT call and save function mx51_clocks_init_dt() now. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

i.MX5 is DT only platforms, so these non-DT device registration helpers is used nowhere. Remove them. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Since i.MX51 becomes a DT only platform, those non-DT support files can be removed now. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Since i.MX51 becomes DT only now, we can drop option MACH_IMX51_DT and just use SOC_IMX51 instead. While at it, rename imx51-dt.c to mach-imx51.c to align with the name schema of other IMX DT only platforms. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Shawn Guo authored
After moving SOC_IMX51 support over to device tree, all i.MX5 support becomes device tree only now. So options SOC_IMX5 and SOC_IMX51 can just be under 'Device tree only'. While at it, 'select ARCH_MXC_IOMUX_V3' is dropped, since it's only needed by non-DT build before. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

The platform_data header usb-ehci-mxc.h has a lot of stuff used by only IMX platform code. They shouldn't be really in this header but a IMX platform local header. Create ehci.h and move these stuff into it. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
