Some GDSCs might support a HW control mode, where in the power domain (gdsc) is brought in and out of low power state (while unsued) without any SW assistance, saving power. Such GDSCs can be configured in a HW control mode when powered on until they are explicitly requested to be powered off by software. Signed-off-by:

With commit f4e87150 ("clk: iproc: Make clocks visible options"), COMMON_CLK_IPROC gained a dependency on ARCH_BCM_IPROC, yet CLK_BCM_63XX also selects that option, this causes the following Kconfig warning: warning: (CLK_BCM_63XX) selects COMMON_CLK_IPROC which has unmet direct dependencies ((ARCH_BCM_IPROC || COMPILE_TEST) && COMMON_CLK) Fix this by adding proper depends for COMMON_CLK_IPROC Fixes: f4e87150 ("clk: iproc: Make clocks visible options") Signed-off-by:

In the user manual of A33 SoC, the bit 22 and 23 of pll-mipi control register is called "LDO{1,2}_EN", and according to the BSP source code from Allwinner [1], the LDOs are enabled during the clock's enabling process. The clock failed to generate output if the two LDOs are not enabled. Add the two bits to the clock's gate bits, so that the LDOs are enabled when the PLL is enabled.

The sdcc driver for msm8996/msm8916/msm8974/msm8994 and apq8084 expects a clk_set_rate() on the sdcc rcg clk to set a floor value of supported clk rate closest to the requested rate, by looking up the frequency table. So move all the sdcc rcgs on all these platforms to use the newly introduced clk_rcg2_floor_ops Signed-off-by:

The default behaviour with clk_rcg2_ops is for the clk_round_rate()/clk_set_rate() to return/set a ceil clock rate closest to the requested rate by looking up the corresponding frequency table. However, we do have some instances (mainly sdcc on various platforms) of clients expecting a clk_set_rate() to set a floor value instead. Add a new clk_rcg2_floor_ops to handle this for such specific rcg instances Signed-off-by:

The PLL-MIPI clock is somewhat special as it has its own LDOs which need to be turned on for this PLL to actually work and output a clock signal. Add the 2 LDO enable bits to the gate bits. This fixes issues with the TCON not sending vblank interrupts when the tcon and dot clock are indirectly clocked from the PLL-MIPI clock.

Some parent clocks of the Exynos5433 CMUs must be always enabled to access any register in the given CMU or devices connected to it. For the time being, until a proper solution based on runtime PM is applied, mark those clocks as critical (instead of ignore unused) to prevent disabling them. Reported-by:

Such platforms are msm8916, apq8084 and msm8974. The RPM is a dedicated hardware engine for managing the shared SoC resources in order to keep the lowest power profile. It communicates with other hardware subsystems via shared memory and accepts clock requests, aggregates the requests and turns the clocks on/off or scales them on demand.
