In preparation of dropping interconnect target module platform data in favor of devicetree based data, we must pass swsup idle quirks to the platform data functions. For now, let's only tag the UART modules with the SWSUP_SIDLE_ACT quirk. The other modules will get tagged with swsup quirks as we drop the platform data and test the changes.

We already have the clockactivity quirk set for some modules like i2c, timers and smartreflex. But we're not passing it to the platform functions yet. Let's start doing that in preparation of dropping interconnect target module platform data in favor of device tree based data. Signed-off-by: Tony Lindgren <tony@atomide.com>

We cannot access mcpdm registers at all unless there is an optional pdmclk configured. As this is currently only needed for mcpdm, let's check for mcpdm in sysc_get_clocks(). If it turns out to be needed for other modules too, we can add more flags to the quirks table for this. Signed-off-by: Tony Lindgren <tony@atomide.com>

At least mcpdm needs an optional external clock enabled to function and this clock typically comes from the PMIC. We can detect mcpdm based on the interconnect target module address and set a quirk flag early. To do this, let's initialize the clocks a bit later and add a new function for sysc_init_early_quirks(). Note that we cannot yet enable the early quirks for mcpdm until the optional external clocks are handled in the in the following patch. Signed-off-by: Tony Lindgren <tony@atomide.com>

We can do the rsstctrl a bit later, but need to deassert rstctrl reset before the clocks are enabled if asserted. Let's only init restctrl in sysc_init_resets() and do the reset later on just before we enable the device clocks. Signed-off-by: Tony Lindgren <tony@atomide.com>

We are currently not managing interconnect target module clocks in the for legacy platform data based case. This causes a problem for using the platform data based functions when dropping the platform data for the interconnect target module configuration. To avoid a situation where we need to populate the main and optional clocks also for the platform data based functions, let's just manage the clocks directly in ti-sysc driver. This means that until the interconnect target module confugration platform data is dropped our use count for clk_enable() will be 2 instead of 1. Signed-off-by: Tony Lindgren <tony@atomide.com>

The platform data based init functions typically reset the interconnect target module configure the registers. As we may need the interconnect target module specific quirks configured based on the revision register, we want to move the platform data based init to happen later. Let's allocate mdata as needed so it's available for sysc_legacy_init() that we call with module clocks enabled from sysc_init_module(). Signed-off-by: Tony Lindgren <tony@atomide.com>

The first thing we want to do is just read the module revision register to be able to configure the module specific quirks and configure the module registers. As the interconnect target module may not yet be properly configured and may need a reset first, we don't want to use pm_runtime_get() at this point. To read the revision register, let's just enable the all the clocks for the interconnect target module during init even if the optional clocks are not needed. That way we can read the revision register to configure the quirks needed for PM runtime. Signed-off-by: Tony Lindgren <tony@atomide.com>

At least McPDM module depends on an external optional clock to be usable. To make handling of the McPDM clock easier in the following patches, let's add separate functions for handling the main clocks and the optional clocks. Let's also add error handling to shut down already enabled clocks while at it. Signed-off-by: Tony Lindgren <tony@atomide.com>

With ti-sysc interconnect target module, we can allocate struct omap_hwmod data based on the devicetree data. This allows dropping the static SoC specific data eventually so we will only boot with data we actually need. To allocate struct omap_hwmod dynamically, we need to add a mutex for modifying the list, and remove __init for few functions. Note that we are not initialized oh->_clk or the optional clocks and their related quirks. That can be directly handled by the interconnect target module driver.

For dynamically allocated struct hwmod entries probing with ti-sysc interconnect target module driver, we need to specify the initial default state the same way as we do for the platform data cases. Let's prepare for that by adding _HWMOD_STATE_DEFAULT that we can then use to set the initial default state without a need to add similar CONFIG_PM handling in multiple places.

For dynamically allocated sysconfig data we only need to allocate a new class for the cases where the class is shared. For dynamically allocated struct omap_hwmod we will always allocate a new class. Let's add detection for when we need to allocate a new class by comparing the class name against the module name. If they match, there's no need to allocate a new calls as we don't have case of mixed platform data and dts data initialized modules for the same class. Let's also move the init of class data inside the spinlock. Cc: Paul Walmsley <paul@pwsan.com> Cc: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Commit 747834ab ("ARM: OMAP2+: hwmod: revise hardreset behavior") made the call to _enable() conditional based on no oh->rst_lines_cnt. This caused the return value to be potentially uninitialized. Curiously we see no compiler warnings for this, probably as this gets inlined. We call _setup_reset() from _setup() and only _setup_postsetup() if the return value is zero. Currently the return value can be uninitialized for cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.
