2021-09-17clk: ti: k3: Update driver to account for divider flagsSuman Anna1-2/+2
The K3 SoCs have some PLL output clocks (POSTDIV clocks) which in turn serve as inputs to other HSDIV output clocks. These clocks use the actual value to compute the divider clock rate, and need to be registered with the CLK_DIVIDER_ONE_BASED flags. The current k3-clk driver and data lacks the infrastructure to pass in divider flags. Update the driver and data to account for these divider flags.

2021-09-17clk: ti: k3-pll: Change DIV_CTRL programming to read-modify-writeDave Gerlach1-2/+11
There are three different divider values in the DIV_CTRL register controlled by the k3-pll driver. Currently the ti_pll_clk_set_rate function writes the entire register when programming plld, even though plld only resides in the lower 6 bits. Change the plld programming to read-modify-write to only affect the relevant bits for plld and to preserve the other two divider values present in the upper 16 bits, otherwise they will always get set to zero when programming plld.

2021-06-17clk: k210: Re-add support for setting rateSean Anderson1-5/+84
This adds support for setting clock rates, which was left out of the initial CCF expunging. There are several tricky bits here, mostly related to the PLLS: * The PLL's bypass is broken. If the PLL is reconfigured, any child clocks will be stopped. * PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent stopping the CPU while we configure PLL0's rate, ACLK is reparented to IN0 while PLL0 is disabled. * PLL1 is the parent of the AISRAM clock. This clock cannot be reparented, so we instead just disallow changing PLL1's rate after relocation (when we are using the AISRAM).

2021-06-17clk: k210: Rewrite to remove CCFSean Anderson3-523/+439
This is effectively a complete rewrite to remove all dependency on CCF. The code is now smaller, and so is the binary. It also takes up less memory at runtime (since we don't have to create 40 udevices). In general, I am much happier with this driver as much of the complexity and late binding has been removed. The k210_*_params structs which were previously used to initialize CCF clocks are now used as the complete configuration. Since we can write our own division logic, we can now do away with several "half" clocks which only existed to provide constant factors of two. The clock IDs have been renumbered to remove unused clocks. This may not be the last time they are renumbered, since we have diverged with Linux. There are also still a few clocks left out which may need to be added back in. In general, I have tried to leave out behavioral changes. However, there is a small bugfix regarding ACLK. According to the technical reference manual, its mux comes *after* its divider (which is present only for PLL0). This would have required yet another intermediate clock to fix with CCF, but with the new driver it is just 2 lines of code :) Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com>
