2024-05-08clk: qcom: clk-alpha-pll: fix rate setting for Stromer PLLsGabor Juhos1-0/+2
The clk_alpha_pll_stromer_set_rate() function writes inproper values into the ALPHA_VAL{,_U} registers which results in wrong clock rates when the alpha value is used. The broken behaviour can be seen on IPQ5018 for example, when dynamic scaling sets the CPU frequency to 800000 KHz. In this case the CPU cores are running only at 792031 KHz: # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq 800000 # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 792031 This happens because the function ignores the fact that the alpha value calculated by the alpha_pll_round_rate() function is only 32 bits wide which must be extended to 40 bits if it is used on a hardware which supports 40 bits wide values. Extend the clk_alpha_pll_stromer_set_rate() function to convert the alpha value to 40 bits before wrinting that into the registers in order to ensure that the hardware really uses the requested rate. After the change the CPU frequency is correct: # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq 800000 # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 800000 Cc: stable@vger.kernel.org Fixes: e47a4f55f240 ("clk: qcom: clk-alpha-pll: Add support for Stromer PLLs") Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Gabor Juhos <j4g8y7@gmail.com> Link: https://lore.kernel.org/r/20240328-alpha-pll-fix-stromer-set-rate-v3-1-1b79714c78bc@gmail.com Signed-off-by: Bjorn Andersson <andersson@kernel.org>

2024-04-21clk: qcom: clk-alpha-pll: remove invalid Stromer register offsetGabor Juhos1-1/+0
The offset of the CONFIG_CTL_U register defined for the Stromer PLL is wrong. It is not aligned on a 4 bytes boundary which might causes errors in regmap operations. Maybe the intention behind of using the 0xff value was to indicate that the register is not implemented in the PLL, but this is not verified anywhere in the code. Moreover, this value is not used even in other register offset arrays despite that those PLLs also have unimplemented registers. Additionally, on the Stromer PLLs the current code only touches the CONFIG_CTL_U register if the result of pll_has_64bit_config() is true which condition is not affected by the change. Due to the reasons above, simply remove the CONFIG_CTL_U entry from the Stromer specific array.

2020-07-24clk: qcom: clk-alpha-pll: same regs and ops for trion and lucidJonathan Marek1-41/+17
Fixed ops were already identical, this adds support for non-fixed ops by sharing between trion and lucid. This also changes the names for trion ops to be consistent with the rest. Note LUCID_PCAL_DONE is renamed to TRION_PCAL_DONE because it is wrong for lucid, LUCID_PCAL_DONE should be BIT(27). Next patch will address this.

2020-02-13clk: qcom: alpha-pll: Make error prints more informativeStephen Boyd1-7/+10
I recently ran across this printk error message spewing in my logs Call set rate on the PLL with rounded rates! and I had no idea what clk that was or what rate was failing to round properly. Make the printk more informative by telling us what went wrong and also add the name of the clk that's failing to change rate. Furthermore, update the other printks in this file with the clk name each time so we know what clk we're talking about.
