From 28d3f06e56baa9c6e2c8e1d9e5fd663138c08b92 Mon Sep 17 00:00:00 2001 From: Abhishek Sahu Date: Thu, 28 Sep 2017 23:20:40 +0530 Subject: clk: qcom: support for alpha pll properties MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Alpha PLL is a generic name used for QCOM PLLs which uses L and Alpha values for configuring the integer and fractional part. QCOM SoCs use different types of Alpha PLLs for which basic software configuration part is common with following differences. 1. All these PLLs have the same basic registers like PLL_MODE, L_VAL, ALPHA_VAL but some of the register offsets are different between PLLs types. 2. The dynamic programming sequence is different in some of the Alpha PLLs 3. Some of the PLLs don’t have 64 bit config control, 64 bit user control, VCO configuration, etc. Signed-off-by: Abhishek Sahu Signed-off-by: Stephen Boyd --- drivers/clk/qcom/clk-alpha-pll.c | 130

which doesn't work work properly for 16-bit ones. The alpha value is calculated on the basis of ALPHA_BITWIDTH to make the computation easy for 40 bit alpha. After calculating the 32 bit alpha, it is converted to 40 bit alpha by making lower bits zero. But if actual alpha register width is less than ALPHA_BITWIDTH, then the actual width can be used for calculation. This also means, during the 40 bit alpha pll set rate path, the lower alpha register is not configured Change the code to calculate the rate and register values from 'alpha_width' instead of hard-coding it so that it can work for the different widths that are supported.

We do check the individual fields before using them, but not the structure pointer itself. This may have the usual nasty consequences when the pointer is dereferenced, most likely when checking one the field during the initialization. This is fixed by returning an error on clock register if the ops pointer is NULL.

It should bail out if the request would not result in a rate a change. This is important when the rate is not exactly what is requested, which is fairly common with PLLs. Ex: provider able to give any rate with steps of 100Hz - 1st consumer request 48000Hz and gets it. - 2nd consumer request 48010Hz as well. If we were to perform the usual mechanism, we would get 48000Hz as well. The clock would not change so there is no point performing any checks to make sure the clock can change, we know it won't.

This may leave the clock in inconsistent state if the rate is out the requested range. Calling clk_core_set_rate() with the closest rate limit could solve the problem but: - The underlying determine_rate() callback needs to account for this corner case (rounding within the range, if possible) - if only round_rate() is available, we rely on luck unfortunately.
