[PATCH 0/6] phy: rockchip: samsung-hdptx: Clock fixes and API transition cleanups

[Cristian Ciocaltea <cristian.ciocaltea@collabora.com>]

This series provides a set of bug fixes and cleanups for the Rockchip
Samsung HDPTX PHY driver.

The first part of the series (i.e. PATCH 1 & 2) addresses clock rate
calculation and synchronization issues.  Specifically, it fixes edge
cases where the PHY PLL is pre-programmed by an external component (like
a bootloader) or when changing the color depth (bpc) while keeping the
modeline constant.  Because the Common Clock Framework .set_rate()
callback might not be invoked if the pixel clock remains unchanged, this
previously led to out-of-sync states between CCF and the actual HDMI PHY
configuration.

The second part focuses on code cleanups and modernizing the register
access.  Now that dw_hdmi_qp driver has fully switched to using
phy_configure(), we can drop the deprecated TMDS rate setup workarounds
and the restrict_rate_change flag logic.  Finally, it refactors the
driver to consistently use standard bitfield macros.
