This series does some minor clean-up to the pch_uart driver, adds support
for the Fish River Island II UART clock quirks, and introduces a user_uartclk
parameter to aid in developing for early and changing hardware.
In order to support an early serial console, we cannot rely on the pch_phub
probe function to setup the CFGCLK register. This series relies on the board
quirks and does not force the setting of the CLKREG in the pch_phub code.
Instead, it aligns with what is the default configuration (defined by firmware)
for a given board. The user_uartclk parameter provides a mechanism to force a
specific uartclk if necessary.
V2: Incorporates Alan Cox's feedback into 2/4: Add Fish River Island II uart
clock quirks, refactoring the clock quirks into a new function and using
a more appropriate name for a reused string variable.
Add support for the two firmware variants for the FRI2.
V3: Rebase on linux-next.git/master rather than linux-2.6.git.
Add module parameter descriptions.
