Other than 'mmc_mux', 'clk_sdio0_ciu' uses a different parent mux clock. Let's add this mux clock as 'sdio0_mux', and correct the parent of 'clk_sdio0_ciu' to be it. Signed-off-by:

UART3 clock rate is doubled in previous commit. This error is not detected until recently a mezzanine board which makes real use of uart3 port (through LS connector of 96boards) was setup and tested on hi3660-hikey960 board. This patch changes clock source rate of clk_factor_uart3 to 100000000. Signed-off-by:

On gcc-4.6, we get a harmless link-time warning: WARNING: vmlinux.o(.text.unlikely+0x196a0): Section mismatch in reference from the function mtk_infrasys_init_early() to the function .init.text:mtk_clk_register_cpumuxes() The function mtk_infrasys_init_early() references the function __init mtk_clk_register_cpumuxes(). This is often because mtk_infrasys_init_early lacks a __init annotation or the annotation of mtk_clk_register_cpumuxes is wrong. Newer compilers inline this function so they don't warn, but marking it __init is the right solution for all versions. Fixes: e9862118 ("clk: mediatek: Add MT2701 clock support") Signed-off-by:

Allowing the lcdif_pre_sel to propagate rate changes to its parent PLL allows more fine grained control over the LCDIF pixel clock rate. For example, the Innovision AT043TN24 LCD panel described in the imx6ul-14x14-evk device tree requires a 9 MHz pixel clock. Before this patch, the lcdif_pre_sel clock rate is fixed, and just setting the lcdif_pred and lcdif_podf dividers only allows to get as close as about 8.44 MHz: pll3 1 1 480000000 0 0 pll3_bypass 1 1 480000000 0 0 pll3_usb_otg 1 1 480000000 0 0 pll3_pfd1_540m 1 1 540000000 0 0 lcdif_pre_sel 1 1 540000000 0 0 lcdif_pred 1 1 67500000 0 0 lcdif_podf 1 1 8437500 0 0 lcdif_pix 1 1 8437500 0 0 Once lcdif_pre_sel is allowed to propagate rate requests to its parent, the actual pixel clock matches the requested value: pll3 1 1 480000000 0 0 pll3_bypass 1 1 480000000 0 0 pll3_usb_otg 1 1 480000000 0 0 pll3_pfd1_540m 1 1 288000000 0 0 lcdif_pre_sel 1 1 288000000 0 0 lcdif_pred 1 1 36000000 0 0 lcdif_podf 1 1 9000000 0 0 lcdif_pix 1 1 9000000 0 0 Signed-off-by:Philipp Zabel <p.zabel@pengutronix.de> Reviewed-by:

On i.MX6 SoCs without VPU (in my case MCIMX6D4AVT10AC), the hdmi driver fails to probe: [ 2.540030] dwhdmi-imx 120000.hdmi: Unsupported HDMI controller (0000:00:00) [ 2.548199] imx-drm display-subsystem: failed to bind 120000.hdmi (ops dw_hdmi_imx_ops): -19 [ 2.557403] imx-drm display-subsystem: master bind failed: -19 That's because hdmi_isfr's parent, video_27m, is not correctly ungated. As explained in commit 5ccc248c ("ARM: imx6q: clk: Add support for mipi_core_cfg clock as a shared clock gate"), video_27m is gated by CCM_CCGR3[CG8]. On i.MX6 SoCs with VPU, the hdmi is working thanks to the CCM_CMEOR[mod_en_ov_vpu] bit which makes the video_27m ungated whatever is in CCM_CCGR3[CG8]. The issue can be reproduced by setting CCMEOR[mod_en_ov_vpu] to 0. Make the HDMI work in every case by setting hdmi_isfr's parent to mipi_core_cfg. Signed-off-by:

The RPM clocks were missing for MSM8660/APQ8060. For this to be completed we need to add a special fixed rate RPM clock that is used for the PLL4 on these SoCs. The rest of the clocks are pretty similar to the other supported platforms. The "active" clock pattern is mirrored in all the clocks. I guess that the PLL4 that clocks the LPASS is actually never used as "active only" since the low-power audio subsystem should be left on when the CPU goes to idle, so that it can be used as a stand-alone MP3 player type of device. The PLL4 seems to be enabled only on behalf of the booting LPASS Hexagon - which will cast its own vote once its booted - and as such we only configure the active state (meaning both states will have same configuration). The result is that PLL4 will be on from prepare() to unprepare() regardless of what the application CPU does. Signed-off-by:

By default, it is assumed that the UTMI clock is generated from a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ field of the SFR_UTMICKTRIM has to be updated to generate the UTMI clock in the proper way. The UTMI clock has a fixed rate of 480 MHz. In fact, there is no multiplier we can configure. The multiplier is managed internally, depending on the reference clock frequency, to achieve the target of 480 MHz. Signed-off-by:

Sometimes we only have one of_clk_del_provider() call in driver error and remove paths, because we're missing a devm_of_clk_add_hw_provider() API. Introduce the API so we can convert drivers to use this and potentially reduce the amount of code needed to remove providers in drivers. Signed-off-by: -
