-Subject: [PATCH] MIPS: ath79: make bootconsole wait for both THRE and TEMT
-
-This makes the ath79 bootconsole behave the same way as the generic 8250
-bootconsole.
-
-Also waiting for TEMT (transmit buffer is empty) instead of just THRE
-(transmit buffer is not full) ensures that all characters have been
-transmitted before the real serial driver starts reconfiguring the serial
-controller (which would sometimes result in garbage being transmitted.)
-This change does not cause a visible performance loss.
-
-In addition, this seems to fix a hang observed in certain configurations on
-many AR7xxx/AR9xxx SoCs during autoconfig of the real serial driver.
-
-A more complete follow-up patch will disable 8250 autoconfig for ath79
-altogether (the serial controller is detected as a 16550A, which is not
-fully compatible with the ath79 serial, and the autoconfig may lead to
-undefined behavior on ath79.)

-bcm2835_pll_off is currently assigning CM_PLL_ANARST to the control
-register, which may lose the other bits that are currently set by the
-clock dividers.
-
-It also now locks during the read/modify/write cycle of both
-registers.

-
-Current clamping of a normal divider allows a value < 1 to be valid.
-
-A divider of < 1 would actually only be possible if we had a PLL...
-
-So this patch clamps the divider to 1.
