Ajit Pandey 868e843e52 clk: qcom: clk-alpha-pll: Fix CAL_L_VAL override for LUCID EVO PLL 
commit fff617979f upstream.

In LUCID EVO PLL CAL_L_VAL and L_VAL bitfields are part of single
PLL_L_VAL register. Update for L_VAL bitfield values in PLL_L_VAL
register using regmap_write() API in __alpha_pll_trion_set_rate
callback will override LUCID EVO PLL initial configuration related
to PLL_CAL_L_VAL bit fields in PLL_L_VAL register.

Observed random PLL lock failures during PLL enable due to such
override in PLL calibration value. Use regmap_update_bits() with
L_VAL bitfield mask instead of regmap_write() API to update only
PLL_L_VAL bitfields in __alpha_pll_trion_set_rate callback.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
