2015-02-03[media] rtl28xxu: add support for RTL2832U/RTL2832 PID filterAntti Palosaari
RTL2832 demod integrated into RTL2832U has PID filter. PID filtering is provided by rtl2832 demod driver. Add support for it. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-02-03[media] rtl2832: implement PID filterAntti Palosaari
Implement PID filter. This demod has PID filter size of 32 PIDs. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-02-03[media] rtl2832: define more demod lock statusesAntti Palosaari
Demod lock flags are derived from demod state machine states. States are running from 1 to 11, where highest state 11 means demod is fully locked and streaming. Naturally smaller state numbers means there is some partial locks. Define now state 10 as missing synch and lock.

2015-02-03[media] rtl28xxu: use demod mux I2C adapter for every tunerAntti Palosaari

2015-02-03[media] rtl2832: rename driver state variable from 'priv' to 'dev'Antti Palosaari

2015-02-03[media] rtl2832: remove exported resourcesAntti Palosaari

2015-02-03[media] rtl2832: add platform data callbacks for exported resourcesAntti Palosaari

2015-02-03[media] rtl2830: implement own I2C lockingAntti Palosaari
Own I2C locking is needed due to two special reasons: 1) Chips uses multiple register pages/banks on single I2C slave. Page is changed via I2C register access. 2) Chip offers muxed/gated I2C adapter for tuner. Gate/mux is controlled by I2C register access. Due to these reasons, I2C locking did not fit very well.

2015-02-03ahci_xgene: Fix the dma state machine lockup for the ATA_CMD_SMART PIO mode ↵Suman Tripathi
command. This patch addresses the issue with ATA_CMD_SMART pio mode command for enumeration and device detection with ATA devices. The X-Gene AHCI controller has an errata in which it cannot clear the BSY bit after the PIO setup FIS. The dma state machine enters CMFatalErrorUpdate state and locks up. It is the same issue as in the commit 2a0bdff6b958 ("ahci-xgene: fix the dma state machine lockup for the IDENTIFY DEVICE PIO mode command"). For example : without this patch it results in READ DMA command failure as shown below : [ 126.700072] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [ 126.707089] ata2.00: failed command: READ DMA [ 126.711426] ata2.00: cmd c8/00:08:00:55:57/00:00:00:00:00/e1 tag 1 dma 4096 in [ 126.711426] res 40/00:ff:00:00:00/00:00:00:00:00/40 Emask 0x4 (timeout) [ 126.725956] ata2.00: status: { DRDY } Signed-off-by: Suman Tripathi <stripathi@apm.com> Reported-by: Mark Langsdorf <mlangsdo@redhat.com> Signed-off-by: Tejun Heo <tj@kernel.org>

2015-02-03ath9k: Check WOW triggers properlySujith Manoharan

2015-02-03ath9k: Fix wow init/deinitSujith Manoharan
Registering the card as a wakeup source needs to be done once, during initialization. When the WOW configuration changes, the card's status as wakeup source needs to be changed too and this is done via the set_wakeup() callback.

2015-02-03ath9k: Check early for multi-vif/STA conditionsSujith Manoharan

2015-02-03ath9k: Remove redundant device_can_wakeup() checkSujith Manoharan
WOW capability is registered with mac80211 only when the device has the ability to wakeup, so there is no need to check in the suspend() routine. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
