* [PATCH 1/2] rtc: sunxi: Add new compatibles
From: Maxime Ripard @ 2014-02-02 13:50 UTC (permalink / raw)
To: linux-arm-kernel
The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Add compatibles
matching the other pattern to the RTC driver for consistency, and keep the
older one for backward compatibility.

* [PATCH 1/2] i2c: sunxi: Add new i2c compatibles
From: Maxime Ripard @ 2014-02-02 13:39 UTC (permalink / raw)
To: linux-arm-kernel
The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Add compatibles
matching the other pattern to the i2c driver for consistency, and keep the
older one for backward compatibility.

* [PATCH 1/2] clk: sunxi: Add new clock compatibles
From: Maxime Ripard @ 2014-02-02 13:36 UTC (permalink / raw)
To: linux-arm-kernel
The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Add compatibles
matching the other pattern to the clock driver for consistency, and keep the
older one for backward compatibility.

I discussed these patches with Rob Clark recently, and the conclusion
we came to is that I'll merge them into a git tree, test them, and
once I'm happy I'll send a pull request as appropriate.
I'll go through them later today. Those patches which have been re-
posted without any change for the last few times (the first few) I'll
take into my git tree today so you don't have to keep re-posting them
(more importantly, I won't have to keep on looking at them either.)

Note that the context for the MPC512x SPI driver will change in
3.14-rc1, so you will have to rebase after the merge window.

Reading the diff in the SPI master driver, the change appears to
be balanced, and replacing 'goto free_master' with immediate
return looks appropriate.
Can't comment on the correctness of removing the spi_master_put()
call when switching from spi_alloc_master() to
devm_spi_alloc_master(). This gets discussed in the other
subthread, dealing with the generic subsystem approach.

FYI, I just tested Linus' tip, and NFS is still broken.

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up. Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".

+Cirrus Logic CLPS711X Interrupt Controller
+
+Required properties:
+
+- compatible: Should be "cirrus,clps711x-intc".
+- reg: Specifies base physical address of the registers set.
+- interrupt-controller: Identifies the node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source. The value shall be 1.
+
+The interrupt sources are as follows:
+ID Name Description
+---------------------------
+1: BLINT Battery low (FIQ)
+3: MCINT Media changed (FIQ)
+4: CSINT CODEC sound
+5: EINT1 External 1
+6: EINT2 External 2
+7: EINT3 External 3
+8: TC1OI TC1 under flow
+9: TC2OI TC2 under flow
+10: RTCMI RTC compare match
+11: TINT 64Hz tick
+12: UTXINT1 UART1 transmit FIFO half empty
+13: URXINT1 UART1 receive FIFO half full
+14: UMSINT UART1 modem status changed
+15: SSEOTI SSI1 end of transfer
+16: KBDINT Keyboard
+17: SS2RX SSI2 receive FIFO half or greater full
+18: SS2TX SSI2 transmit FIFO less than half empty
+28: UTXINT2 UART2 transmit FIFO half empty
+29: URXINT2 UART2 receive FIFO half full
+32: DAIINT DAI interface (FIQ)
+
+Example:
+ intc: interrupt-controller {
+ compatible = "cirrus,clps711x-intc";
+ reg = <0x80000000 0x4000>;
+ interrupt-controller;
+ #interrupt-cells = <1>;

I actually noticed a rather strange behavior when the clock polarity was
inverted as well. The flicker was not always there in my case either, but I used
parallel LCD .

* [PATCH 3/3] ARM: fix HAVE_ARM_TWD selection for OMAP and shmobile
From: Rob Herring @ 2014-02-01 22:35 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1391294144-27787-1-git-send-email-robherring2@gmail.com>
From: Rob Herring <robh@kernel.org>
The selection of HAVE_ARM_TWD for OMAP and shmobile depend on LOCAL_TIMER
which no longer exists. They should depend on SMP instead.
