[PATCH 03/10] soc: amlogic: clk-measure: Add support for more SoCs

[sashiko-bot at kernel.org]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Low] The `clk_msr_a9` array is missing the `const` qualifier, causing it to be placed in the modifiable `.data` section instead of the read-only `.rodata` section.
- [Low] Possible typo in the clock name "exit_Tsin_B_CLK_IN" for ID 26 in the `clk_msr_a9` array.

soc: amlogic: clk-measure: Add support for more SoCs

This commit adds clk-measure driver support for several Amlogic SoCs
including A5, A4, S7, S7D, S6, and A9.

[Severity: Low]
Is the missing const qualifier here intentional? Without const, this array is
placed in the modifiable data section instead of the read-only rodata section,
increasing the mutable memory footprint.

Other clock ID tables introduced in this patch, such as clk_msr_a5 and
clk_msr_s7, are properly defined as static const struct meson_msr_id. Because
the driver only copies the elements from these arrays during device probe,
the original template array does not need to be mutable.

[Severity: Low]
Does this string contain a typo? The name "exit_Tsin_B_CLK_IN" is exported to
userspace via debugfs.

In similar SoC definitions like clk_msr_s6, the corresponding ID 26 is named
"ext_Tsin_B_CLK_IN", likely standing for external. Using "exit" here instead
of "ext" could confuse users or break userspace scripts expecting consistent
naming across SoCs.
