2010-03-07tmio_mmc: Remove const from platform data V3Magnus Damm
Remove const from the tmio-mmc platform data hclk V3. This change makes it possible to remove the type cast from the sh_mobile_sdhi driver which is using the clock framework to get the clock rate. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-03-07tmio_mmc: Use 100ms mmc_detect_change() delayMagnus Damm
This patch changes the tmio_mmc driver to wait 100ms before checking the card detect status. This type of delay is quite common among mmc drivers, it seems that most hardware platforms need to give the hardware some time to settle before checking card availabilty. Hotplug is half-broken without this patch on the sh7724 Ecovec board. Hot insertion seems ok but eject is never detected without this patch.

2010-03-07tmio_mmc: Keep card-detect interrupts enabledGuennadi Liakhovetski
On SuperH platforms the SDHI controller does not produce any command IRQs after a completed IO. This leads to card-detect interrupts staying disabled. Do not disable card-detect interrupts on DATA IRQs.

2010-03-07mfd: Disable TWL4030/5030 I2C1/I2C4 internal pull-upsMoiz Sonasath
This patch disables TWL4030/5030 I2C1 adn I2C4(SR) internal pull-up, to use only the external HW resistor >=470 Ohm for the assured functionality in HS mode. While testing the I2C in High Speed mode, it was discovered that without a proper pull-up resistor, there is data corruption during multi-byte transfer. RTC(time_set) test case was used for testing. From the analysis done, it was concluded that ideally we need a pull-up of 1.6k Ohm(recomended) or atleast 470 Ohm or greater for assured performance in HS mode.

2010-03-07mfd: Use AB3100 MFD core IRQ for interrupt randomnessLinus Walleij
This reintroduces the entropy sampling of the AB3100 IRQ as the IRQF_SAMPLE_RANDOM is going out according to the feature removal schedule. I'm trying to do this the right way then, so CC:ing some random people for a quick review. We add entropy for interrupt events in the AB3100 which are truly random in nature, like external cables being connected, voltages on batteries dropping below certain ranges, ADC triggers or overheating.

2010-03-07mfd: Add HTCPLD driverCory Maccarrone
This change introduces a driver for the HTC PLD chip found on some smartphones, such as the HTC Wizard and HTC Herald. It works through the I2C bus and acts as a GPIO extender. Specifically: * it can have several sub-devices, each with its own I2C address * Each sub-device provides 8 output and 8 input pins * The chip attaches to one GPIO to signal when any of the input GPIOs change -- at which point all chips must be scanned for changes This driver implements the GPIOs throught the kernel's GPIO and IRQ framework. This allows any GPIO-servicing drivers to operate on htcpld pins, such as the gpio-keys and gpio-leds drivers.

2010-03-07mfd: Support 88pm8606 in 860x driverHaojian Zhuang
88PM8606 and 88PM8607 are two discrete chips used for power management. Hardware designer can use them together or only one of them according to requirement. There's some logic tightly linked between these two chips. For example, USB charger driver needs to access both chips by I2C interface. Now share one driver to these two devices. Only one I2C client is identified in platform init data. If another chip is also used, user should mark it in companion_addr field of platform init data. Then driver could create another I2C client for the companion chip. All I2C operations are accessed by 860x-i2c driver. In order to support both I2C client address, the read/write API is changed in below. reg_read(client, offset) reg_write(client, offset, data) The benefit is that client drivers only need one kind of read/write API. I2C and MFD driver can be shared in both 8606 and 8607. Since API is changed, update API in 8607 regulator driver.

2010-03-07mfd: Correct use after free for t7l66xbJulia Lawall
The structure t7l66xb should not be freed before the subsequent references to its fields in the arguments to clk_put. Furthermore, this structure is allocated near the beginning of the function, and a goto to the label err_noirq appears after a successful allocation, so it would seem that the kfree should be moved down below this label. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; identifier f; iterator I; statement S; @@ *kfree(x); ... when != &x when != x = e when != I(x,...)
