soc: imx8m: Enable OCOTP clock for imx8mm before reading registers

2023-09-24T12:50:27+00:00

Commit 836fb30949d9 ("soc: imx8m: Enable OCOTP clock before reading the
register") added configuration to enable the OCOTP clock before
attempting to read from the associated registers.

This same kexec issue is present with the imx8m SoCs that use the
imx8mm_soc_uid function (e.g. imx8mp). This requires the imx8mm_soc_uid
function to configure the OCOTP clock before accessing the associated
registers. This change implements the same clock enable functionality
that is present in the imx8mq_soc_revision function for the
imx8mm_soc_uid function.

soc: imx: Move power-domain drivers to the genpd dir

2023-07-11T13:30:09+00:00

To simplify with maintenance let's move the imx power-domain drivers to the
new genpd directory. Going forward, patches are intended to be managed
through a separate git tree, according to MAINTAINERS.

soc: imx: imx8m-blk-ctrl: reordering the fields

2023-03-27T01:52:41+00:00

The clang-analyzer reports:
"Excessive padding in 'struct imx8m_blk_ctrl_domain_data'
(12 padding bytes, where 4 is optimal). Optimal fields order: name,
clk_names, path_names, gpc_name, num_clks, num_paths, rst_mask, clk_mask,
mipi_phy_rst_mask, consider reordering the fields or adding explicit
padding members [clang-analyzer-optin.performance.Padding]
   struct imx8m_blk_ctrl_domain_data {"

So reordering the fields.
