    Subject[PATCH RESEND v2 0/5] Modify MxL's CGU clk driver to make it secure boot compatible
    Date
    * Rebase on latest 6.0 clk linux tree and resend patch series because of
    no response from anyone so far. Please let me know if anyone has any
    concerns about these changes. Thanks.

    MxL's CGU driver was found to be lacking below required features. Add these
    required lacking features:

    1. Since it is a core driver, it has to conform to secure boot & secure
    access architecture. In order for the register accesses to be secure
    access compliant, it needs regmap support as per our security architecture.
    Hence, replace direct read/writel with regmap based IO. Also remove spinlocks
    because they are no longer necessary because regmap uses its own lock.

    2. There are some gate clocks which are used by the power mgmt IP to gate when
    a certain power saving mode is activated. These gate clocks can also be
    gated from CGU clk driver. This creates a conflict. To avoid the conflict,
    by default disable gating such gate registers from CGU clk driver. But keep
    a flag to do so for other older IP's which uses same CGU clk IP but does not
    use same power mgmt IP.

    3. Fix two functional bugs found during testing.

    This patch series is based on below git tree:
    git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git


    Rahul Tanwar (5):
    clk: mxl: Switch from direct readl/writel based IO to regmap based IO
    clk: mxl: Remove unnecessary spinlocks
    clk: mxl: Avoid disabling gate clocks from clk driver
    clk: mxl: Add validation for register reads/writes
    clk: mxl: Add a missing flag to allow parent clock rate change
