The i.MX clock updates for 4.4: - A couple of fixes on i.MX31 and i.MX35 clock initialization functions which makes mxc_timer_init() currently be called twice for DT boot. - Increase i.MX6UL AXI bus clock rate to 264MHz which is the optimal design target. - Add a few missing clocks, ADC clock for i.MX7D, OCOTP clock for Vybrid, and SPDIF_GCLK for i.MX6. - A series from Lucas to fix early debug UART clock setup. This is currently a one-off fix for i.MX platform, and can be extended to become a generic solution later.

Correct SPDIF clock setting issue in clock tree, the SPDIF_GCLK is also one clock of SPDIF, which is missed before. We found an issue that imx can't enter low power mode with spdif if IMX6x_CLK_SPDIF is used as the core clock of spdif. Because spdif driver will register IMX6x_CLK_SPDIF clock to regmap, regmap will do clk_prepare in init function, then IMX6x_CLK_SPDIF clock is prepared in probe, so its parent clock (PLL clock) is prepared, the prepare operation of PLL clock is to enable the clock. But I.MX needs all PLL clock is disabled, then it can enter low power mode. So we can't use IMX6x_CLK_SPDIF as the core clock of spdif, the correct spdif core clock is SPDIF_GCLK, which share same gate bit with IMX6x_CLK_SPDIF clock. SPDIF_GCLK's parent clock is ipg clock.

On i.MX6UL, AXI clock rate's design target is 264MHz, but by default it is only set to 198MHz which is NOT good enough for performance, this patch increases AXI clock rate from 198MHz to 264MHz to meet the design target, this is done by switching its parent clock "periph" from 396MHz PFD to 528MHz PLL.

rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not a boolean value. Now, admittedly the "!= 0" doesn't really change the value (0 stays as zero, 1 stays as one), but it's not only redundant, it confuses gcc, and causes gcc to warn about the construct switch (rq_data_dir(req)) { case READ: ... case WRITE: ... that we have in a few drivers. Now, the gcc warning is silly and stupid (it seems to warn not about the switch value having a different type from the case statements, but about _any_ boolean switch value), but in this case the code itself is silly and stupid too, so let's just change it, and get rid of warnings like this: drivers/block/hd.c: In function ‘hd_request’: drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool] switch (rq_data_dir(req)) { The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in commit 5953316d ("block: make rq->cmd_flags be 64-bit") and is presumably because the old code (that just did a logical 'and' with 1) would then end up making the type of rq_data_dir() be u64 too. But if we want to retain the old regular integer type, let's just cast the result to 'int' rather than use that rather odd '!= 0'. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Fix up the writeback plugging introduced in commit d353d758 ("writeback: plug writeback at a high level") that then caused problems due to the unplug happening with a spinlock held. * writeback-plugging: writeback: plug writeback in wb_writeback() and writeback_inodes_wb() Revert "writeback: plug writeback at a high level"
-
由 Linus Torvalds 提交于
We had to revert the pluggin in writeback_sb_inodes() because the wb->list_lock is held, but we could easily plug at a higher level before taking that lock, and unplug after releasing it. This does that. Chris will run performance numbers, just to verify that this approach is comparable to the alternative (we could just drop and re-take the lock around the blk_finish_plug() rather than these two commits. I'd have preferred waiting for actual performance numbers before picking one approach over the other, but I don't want to release rc1 with the known "sleeping function called from invalid context" issue, so I'll pick this cleanup version for now. But if the numbers show that we really want to plug just at the writeback_sb_inodes() level, and we should just play ugly games with the spinlock, we'll switch to that.

I didn't notice this when merging the thermal code from Zhang, but his merge (commit 5a924a07: "Merge branches 'thermal-core' and 'thermal-intel' of .git into next") of the thermal-core and thermal-intel branches was wrong. In thermal-core, commit 17e8351a ("thermal: consistently use int for temperatures") converted the thermal layer to use "int" for temperatures. But in parallel, in the thermal-intel branch commit d0a12625 ("thermal: Add Intel PCH thermal driver") added support for the intel PCH thermal sensor using the old interfaces that used "unsigned long" pointers. This resulted in warnings like this: drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types] .get_temp = pch_thermal_get_temp, ^ drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization for ‘tzd_ops.get_temp’) drivers/thermal/intel_pch_thermal.c:186:19: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types] .get_trip_temp = pch_get_trip_temp, ^ drivers/thermal/intel_pch_thermal.c:186:19: note: (near initialization for ‘tzd_ops.get_trip_temp’) This fixes it.
