| | | | | | | | | | | | We no longer have users for the compatibility clocks and we can drop them. These are old duplicate clocks for what we using.

* clk: ti: am33xx: Keep am3 l3 main clock always on for genpdTony Lindgren2020-11-161-0/+2
| | | | | | | | | | | | | | | | | In order for suspend and resume to work with genpd on am3, we must keep l3 main clock always on. Otherwise prm_omap driver will shut down the l3 main clock on suspend when simple-pm-bus and GENPD_FLAG_PM_CLK are used. Note that we already keep the l3 main clock always on with the legacy platform code. Later on we may want to start managing the l3 main clock with a dedicated interconnect driver instead of using simple-pm-bus and GENPD_FLAG_PM_CLK.

* clk: ti: am33xx: fix RTC clock parentTero Kristo2020-05-121-1/+1
| | | | | | | | | | | | | | Right now, trying to use RTC purely with the ti-sysc / clkctrl framework fails to enable the RTC module properly. Based on experimentation, this appears to be because RTC is sourced from the clkdiv32k optional clock. TRM is not very clear on this topic, but fix the RTC to use the proper source clock nevertheless.

* clk: ti: am33xx: drop idlest polling from gfx clockTero Kristo2019-10-311-1/+1
| | | | | | | | | | | Due to the way ti sysc and hardreset line control is now implemented, it is not possible to poll the clock status for gfx clock independent of hardreset line control. Thus, add a flag to prevent handling this status bit from clock driver. Correct sequencing of events is guaranteed by ti-sysc bus driver.

* clk: ti: am33xx: drop idlest polling from pruss clkctrl clockTero Kristo2019-10-311-1/+1
| | | | | | | | | | | | | | The PRUSS module on AM33xx SoCs has a hardreset line and is controlled by a PRCM reset line. Any clkctrl enable/disable operations cannot be checked for module enabled/disabled status independent of the reset operation, and this causes some unwanted timeouts in the kernel and unbalanced states for the PRUSS clocks. These details should be handled by the driver integration code itself. Add the CLKF_NO_IDLEST flag to the PRUSS clkctrl clock so that these module status checks are skipped.

* clk: ti: am33xx: add new clkctrl data for am33xxTero Kristo2018-10-031-1/+243
| | | | | | | | | | | The new clkctrl data layout for am33xx is split based on clockdomain boundaries. Previously the split was based on CM boundaries. This patch adds the new data as separate data entity, retaining the compatibility data also for now. The compatibility data can be removed once no longer needed.
