According to MT7622 Reference Manual for Development Board v1.0 the PWM
unit found in the MT7622 SoC also comes with the PWM_CK_26M_SEL register
at offset 0x210 just like other modern MediaTek ARM64 SoCs.
And also MT7622 sets that register to 0x00000001 on reset which is
described as 'Select 26M fix CLK as BCLK' in the datasheet.
Hence set has_ck_26m_sel to true also for MT7622 which results in the
driver writing 0 to the PWM_CK_26M_SEL register which is described as
'Select bus CLK as BCLK'.

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.
