|\ | | | | | | | | | | | | | | | | | | | | | | v4.4-next/dt-samsung Device Tree improvements for Exynos based boards (updated pull request): 1. Enable DMA on Exynos4 serial ports. This old patch uncovered a number of other issues in dmaengine and samsung serial driver. All of known issues are resolved so finally enable the DMA for UART. 2. Fix incorrect location of display-timings node (FIMD->DP node) on Arndale, SMDK5250 and SMDK5240 boards. 3. Minor cleanups.
| * ARM: dts: Remove regulator-compatible usage in exynos4412-trats2Javier Martinez Canillas2015-10-061-70/+35
| | | | | | | | | | | | | | | | | | | | | | The regulator-compatible property from the regulator DT binding was deprecated and the correct approach is to use the node's name. This patch has no functional changes but by not using a deprecated property, new DTS based on this one will not carry the same issue.

* | ARM: dts: Add Exynos5250 Snow Rev5+ support on exynos5250-snow-rev5Javier Martinez Canillas2015-09-304-667/+736
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 2 revisions of the Exynos5250 Snow Chromebook that were shipped: Rev4 and Rev5. The only difference between these 2 revisions is the codec, Rev4 has a max98095 codec while Rev5 has a max98090. Mainline only supports Rev4 so this patch moves the common device nodes to a DTSI file and adds a DTS for the Exynos5250 Snow Rev5. The Snow Rev5 DTS is based on the DTS found in the ChromiumOS 3.8 tree.

No green and red LEDs (except standard red power LED). 2. Only two PWM outputs are used (fan and blue LED) 3. No audio codec. 4. Two USB3 ports in host mode (no micro USB3 connector for OTG). 5. Realtek RTL8153-CG gigabit network adapter (instead of SMSC9514). 6. Additional connector with IO ports (I2S_0, I2C_5). 7. No DisplayPort (like XU3-Lite). 8.

* | blk: rq_data_dir() should not return a booleanLinus Torvalds2015-09-121-1/+1

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 5953316dbf90 ("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: Linus Torvalds <torvalds@linux-foundation.org>
