On Hi6220, there have some clocks which can use mailbox channel to send messages to power controller to change frequency; this includes CPU, GPU and DDR clocks. For dynamic frequency scaling, firstly need write the frequency value to SRAM region, and then send message to mailbox to trigger power controller to handle this requirement. This driver will use syscon APIs to pass SRAM memory region and use common mailbox APIs for channels accessing. This init driver will support cpu frequency change firstly. Signed-off-by:

PLL VCO frequency is given by Fvco = Fref * 2 * NF / NR in integer-N mode, or by Fvco = Fref * SSN / NR in Spread Spectrum (fractional-N) mode. Thus fix the missing part of NR Signed-off-by:

I cannot believe that I spend quite a lot time in finding this bug. It seems a pitfall people tend to fall in. In "int64 = int32 * int32", conversion from 32-bits to 64-bits comes after the multiplication. So this statement may not work as expected. Signed-off-by:

The debug base clock can be bypassed from the main PLL to the OSC1 clock. The bypass register is the staysoc1(0x10) register that is in the clock manager. This patch adds the option to get the correct parent for the debug base clock. Signed-off-by:

This driver uses __clk_get_name() when it's dealing with struct clk_hw pointers. Use the simpler form so that we can get rid of the clk member in struct clk_hw one day. Acked-by:

We're removing struct clk from the clk provider API. This code is calling the consumer APIs to change the parent to a 1 MHz fixed rate clock for each of the clocks that the driver provides. Move to using the assigned-clock-parents DT property for this instead. Because this is an ABI break, detect if the property is missing and fall back to setting the parent explicitly before the clocks are registered. Acked-by:

Neither spdif_src nor spdif_pll exists, judging by the vendor kernel in both cases spdif_pre was meant. This brings the naming in line and hierachy in line with that of sclk_i2s0. Also allow sclk_spdif and spdif_frac to change their parents rate as that the upstream dividers are purely there to feed sclk_spdif Signed-off-by:

While children of orphan clocks are not carried in the orphan-list itself, they're nevertheless orphans in their own right as they also don't have an input-rate available. To ease tracking if a clock is an orphan or has an orphan in its parent path introduce an orphan field into struct clk and update it and the fields in child-clocks when a clock gets added or removed from the orphan-list.

The gates were handled with a common piece of framework that was registering all gates array, that was not using the CLK_OF_DECLARE logic, and was not using clock-indices but some private masks that were pretty much equivalent. Move this code in a new driver that handles all the gates array and solves both these issues. Signed-off-by:
