"nsscc-qca8k is accessed via an MDIO bus"

"there is a special MDIO frame sequence"

"which needs to be sent to the device"

the following indentation splat from checkpatch

CHECK: Alignment should match open parenthesis
#2071: FILE: drivers/clk/qcom/nsscc-qca8k.c:2004:
+ ret = __mdiobus_write(bus, switch_phy_id, (reg |
QCA8K_REG_DATA_UPPER_16_BITS),
+ upper_16_bits(val));

CHECK: Alignment should match open parenthesis
#2131: FILE: drivers/clk/qcom/nsscc-qca8k.c:2064:
+static int qca8k_regmap_update_bits(void *context, unsigned int regaddr,
+ unsigned int mask, unsigned int value)

total: 0 errors, 1 warnings, 2 checks, 2162 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
mechanically convert to the typical style using --fix or
--fix-inplace.

0004-clk-qcom-add-clock-controller-driver-for-qca8386-qca.patch has
style problems, please review.

Once fixed
