The DIV_ROUND_CLOSEST_ULL() macro accepts a 64bit dividend and 32bit divisor. This leads to truncation of the divisor, which is the Z or Z2 parent clock frequency in HZ, on platforms where frequency of that clock is greater than UINT32_MAX Hz. To resolve this problem the DIV64_U64_ROUND_CLOSEST() macro, which takes on an unsigned 64bit dividend and divisor, is used. An earlier version of this patch made use of the existing DIV_ROUND_CLOSEST() macro, which accepts the prevailing type of the dividend and divisor. However, this does not compile on 32bit systems, such as i386 and mips, when called with the types used at this call site, an unsigned long long dividend and unsigned long divisor. This work is in preparation for supporting the Z2 clock on the R-Car Gen3 E3 (r8a77990) SoC which has a 4.8GHz parent clock.

Therefore, when cpg_sd_clock_set_rate() sets the clock rate acquired by cpg_sd_clock_round_rate(), an error may occur. This is not conform the clk API design. This patch fixes that by making sure cpg_sd_clock_calc_div() considers only the division values defined in cpg_sd_div_table[]. With this fix, the cpg_sd_clock_round_rate() always return a support clock rate.

From 23fe31dedb7b1836cc23666afc1a9c67ed7de775 Mon Sep 17 00:00:00 2001 From: Weiyi Lu Date: Tue, 5 Mar 2019 13:05:44 +0800 Subject: [PATCH 29/51] clk: mediatek: Add configurable pcw_chg_reg to mtk_pll_data In previous MediaTek PLL design, it assumes the pcw change control is always on the CON1 register. However, the pcw change bit on MT8183 was moved onto CON0 because the the PCW length of audio PLLs are extended to 32-bit. Add configurable pcw_chg_reg to set the pcw change control register address or using the default control register CON1 if without setting in pll data.

James Liao Date: Tue, 5 Mar 2019 13:05:46 +0800 Subject: [PATCH 31/51] clk: mediatek: Allow changing PLL rate when it is off Some modules may need to change its clock rate before turn on it. So changing PLL's rate when it is off should be allowed. This patch removes PLL enabled check before set rate, so that PLLs can set new frequency even if they are off. On MT8173 for example, ARMPLL's enable bit can be controlled by other HW. That means ARMPLL may be turned on even if we (CPU / SW) set ARMPLL's enable bit as 0. In this case, SW may want and can still change ARMPLL's rate by changing its pcw and postdiv settings. But without this patch, new pcw setting will not be applied because its enable bit is 0.
