SubjectRe: [PATCH] clk: qcom: gcc-sdm845: Use floor ops for sdcc clks
Date
Quoting Stephen Boyd (2019-08-30 12:51:42)
> Some MMC cards fail to enumerate properly when inserted into an MMC slot
> on sdm845 devices. This is because the clk ops for qcom clks round the
> frequency up to the nearest rate instead of down to the nearest rate.
> For example, the MMC driver requests a frequency of 52MHz from
> clk_set_rate() but the qcom implementation for these clks rounds 52MHz
> up to the next supported frequency of 100MHz. The MMC driver could be
> modified to request clk rate ranges but for now we can fix this in the
> clk driver by changing the rounding policy for this clk to be round down
> instead of round up.
