This fixes a bug in the way i2c-algo-bit handles I2C_M_RECV_LEN,
used to implement i2c_smbus_read_block_data(). Previously, in the
absence of PEC (rarely used!) it would NAK the "length" byte:S addr Rd [A] [length] NA
That prevents the subsequent data bytes from being read:
S addr Rd [A] [length] { A [data] }* NA
The primary fix just reorders two code blocks, so the length used
in the "should I NAK now?" check incorporates the data which it
just read from the slave device.However, that move also highlighted other fault handling glitches.
This fixes those by abstracting the RX path ack/nak logic, so it
can be used in more than one location. Also, a few CodingStyle
issues were also resolved.Signed-off-by: David Brownell

It turns out that platform_device.id is a "u32" so testing it for being
nonnegative is useless when setting up an i2c adapte. Instead,
do what the platform_bus code does and test it against the value "-1".Signed-off-by: Jean Delvare

We find that SB700 and SB800 use the same SMBus device ID as SB600, which is
0x4385, instead of the already submitted 0x4395.Besides removing the wrong SB700 device ID, add SB800 support to kernel, by
renaming the PCI_DEVICE_ID_ATI_IXP600_SMBUS into
PCI_DEVICE_ID_ATI_SBX00_SMBUS.Signed-off-by: Shane Huang

Build fixes for isp1301_omap driver. I think an earlier version
of this must have gotten lost somewhere, or maybe it only went
into the Linux-OMAP tree.Also, some whitespace fixes to bring this more into sync with the
version of this found in the Linux-OMAP tree. (That version has
updates for the OTG controller on the OMAP 1710 which break that
functionality on OMAP 161x boards like the H2, so merging all of
it is not currently an option.)Signed-off-by: David Brownell

Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This
includes voltage regulators, Dual slot memory card tranceivers and
real-time clock(RTC).The support for RTC is integrated with this driver only; it is not separate
module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic"
(1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too.The battery keeps the RTC active over power off, so once you set clock
(rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will
behave as expected.Cc: "Jean Delvare"

It depends on tristate I2C and it's trivial to make modular. The
current Kconfig allows I2C=m, I2C_ACORN=y, which doesn't work at
all; alternatives are dependency on I2C=y and making I2C_ACORN
itself a tristate. The latter is the right thing to do...Signed-off-by: Al Viro

There's some redundancy in the tsl2550 initialization sequence. It is

Add an ability to utilize the internal SRAM buffer on ICH4
and newer host controllers to speed up execution of block operations.I've split the code so that it is more clear which block transaction is

we think that the controller has the internal buffer. Then, before every
block transaction, if isich4 is set, we attempt to enable the E32B bit in
SMBAUXCTL register.Signed-off-by: Oleg Ryjkov
