2015-08-10i2c: xiic: Do not continue in case of errors in RxShubhrajyoti Datta1-0/+2
In case of error conditions like Arbitration lost or NACK lets signal the waiting process. Handle error cases in the Rx path Signed-off-by: Shubhrajyoti Datta <shubhraj@xilinx.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2015-08-10i2c: xiic: Service all interrupts in isrShubhrajyoti Datta1-14/+10
Currently only one interrupt is serviced in the isr. In case the multiple interrupts happen simultenously we service and ack only one of them. Check for all the causes in the isr and service them.

2015-08-10i2c: xiic: Remove the Addressed as slave interruptShubhrajyoti Datta1-1/+1
Currently there is no slave mode support in the driver also in the isr we just ack it and do nothing. So disable the AAS interrupt. Signed-off-by: Shubhrajyoti Datta <shubhraj@xilinx.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2015-08-10i2c: xiic: Remove the disabling of interruptsShubhrajyoti Datta1-7/+0
Currently before every transfer the interrupts are disabled. So incase the slave nacks in the middle of the transfer the current transfer is not aborted. Upon enabling the interrupts conditions like NACK , arbitration lost will not be masked. Remove the disabling of the interrupts.

2015-08-10i2c: xiic: Do not reset controller before every transferShubhrajyoti Datta1-1/+0
Currently before every transfer the controller is reinitialised. We are already resetting the controller upon errors so upon every transfer is a performance kill. Remove the same. Signed-off-by: Shubhrajyoti Datta <shubhraj@xilinx.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2015-08-10i2c: pxa: No need to set slave addr for i2c master mode resetVaibhav Hiremath1-1/+1
Normally i2c controller works as master, so slave addr is not needed, or it will impact some slave device (eg. ST NFC chip) i2c accesses, because it has the same i2c address with controller. For example, On the pxa1928 based platform, where PMIC (88pm860) is present @0x30 address on TWSI0 interface, and if we set 0x30 as a slave address in pxa1928 TWSI0 module, all the transactions towards PMIC would go for toss.

Pull MIPS fixes from Ralf Baechle: "Another round of MIPS fixes for 4.2. No area does particularly stand out but we have a two unpleasant ones: - Kernel ptes are marked with a global bit which allows the kernel to share kernel TLB entries between all processes. For this to work both entries of an adjacent even/odd pte pair need to have the global bit set. There has been a subtle race in setting the other entry's global bit since ~ 2000 but it take particularly pathological workloads that essentially do mostly vmalloc/vfree to trigger this. This pull request fixes the 64-bit case but leaves the case of 32 bit CPUs with 64 bit ptes unsolved for now. The unfixed cases affect hardware that is not available in the field yet. - Instruction emulation requires loading instructions from user space but the current fast but simplistic approach will fail on pages that are PROT_EXEC but !PROT_READ. For this reason we temporarily do not permit this permission and will map pages with PROT_EXEC | PROT_READ.

2015-08-06drm/i915: Allow parsing of variable size child device entries from VBTDavid Weinehall1-4/+23
VBT version 196 increased the size of common_child_dev_config. The parser code assumed that the size of this structure would not change. The modified code now copies the amount needed based on the VBT version, and emits a debug message if the VBT version is unknown (too new); since the struct config block won't shrink in newer versions it should be harmless to copy the maximum known size in such cases, so that's what we do, but emitting the warning is probably sensible anyway. In the longer run it might make sense to modify the parser code to use a version/feature mapping, rather than hardcoding things like this, but for now the variants are fairly managable.

2015-08-05hwmon: (g762) Export OF module alias informationJavier Martinez Canillas1-0/+1
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the correct module when the device is added.

The commit 8c7a075da9f7980cc95ffcd7e6621d4a87f20f40 "drm/i2c: tda998x: use drm_hdmi_avi_infoframe_from_display_mode()" also uses hdmi_avi_infoframe_pack() to create the AVI infoframe. This function sets the checksum of the frame and this breaks the second calculation of the checksum done in tda998x_write_if().
