LinuxLists.cc - [PATCH v2 2/3] clk: samsung: gs101: propagate PERIC1 USI SPI clock rate

2024-03-26 17:28:59

Subject: [PATCH v2 2/3] clk: samsung: gs101: propagate PERIC1 USI SPI clock rate

When SPI transfer is being prepared, the spi-s3c64xx driver will call
clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK
is a gate (leaf) clock, so it must propagate the rate change up the
clock tree, so that corresponding MUX/DIV clocks can actually change
their values. Add CLK_SET_RATE_PARENT flag to corresponding clocks for
all USI instances in GS101 PERIC1: USI{0, 9, 10, 11, 12, 13}. This change
involves the following clocks:

PERIC1 USI*:

Clock Div range MUX Selection
-------------------------------------------------------------------
gout_peric1_peric1_top0_ipclk_* - -
dout_peric1_usi*_usi /1..16 -
mout_peric1_usi*_usi_user - {24.5 MHz, 400 MHz}

With input clock of 400 MHz this scheme provides the following IPCLK
rate range, for each USI block:

PERIC1 USI*: 1.5 MHz ... 400 MHz

Accounting for internal /4 divider in SPI blocks, and because the max
SPI frequency is limited at 50 MHz, it gives us next SPI SCK rates:

PERIC1 USI_SPI*: 384 KHz ... 49.9 MHz

Which shall be fine for the applications of the SPI bus.

Note that with this we allow the reparenting of the MUX_USIx clocks to
OSCCLK. Each instance of the USI IP has its own MUX_USI clock, thus the
reparenting of a MUX_USI clock corresponds to a single instance of the
USI IP. The datasheet mentions OSCCLK just in the low-power mode
context, but the downstream driver reparents too the MUX_USI clocks to
OSCCLK. Follow the downstream driver and do the same.

Thanks Tudor for looking into this! I agree with the approach outlined above.
Given that
1) Samsung engineers OK'd it
2) Downstream clock driver does it (and also has other features
enabled like automatic clock gating enabled, which implies it should
not cause any issues there if we enable it in the future upstream).
3) We don't want to change clock frequencies of other IP instances
