* b43: Implement PHY PLL resetRafał Miłecki2014-09-15
| | | | | | | We should reset PLL after changing MAC frequency. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* b43: HT-PHY: Move radio calibration to separated functionsRafał Miłecki2014-09-11
| | | | | | | | Also use b43_radio_wait_value to simplify the code and usleep_range when needed. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: HT-PHY: Move radio preparation into init functionRafał Miłecki2014-09-11
| | | | | | | | | Radio should be prepared only before initialization. We need this to be able to call b43_radio_2059_init conditionally (in the future). This also documents RF control register a bit. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: flush some writes on Broadcom MIPS SoCsRafał Miłecki2014-08-25
| | | | | | | | | | Access to PHY and radio registers is indirect on Broadcom hardware and it seems that addressing on some MIPS SoCs may require flushing. So far this problem was noticed on 0x4716 SoC only (marketing names: BCM4717, BCM4718). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: don't duplicate common PHY read/write opsRafał Miłecki2014-08-25
| | | | | | | | | Most of the PHYs use the same way of accessing registers, so move that code to the shared place. An exception is G-PHY which sometimes access A-PHY regs and requires special handling. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* b43: HT-PHY: do some extra TSSI setup after configuring TXRafał Miłecki2013-04-23
| | | | | | | | | | After b43_phy_ht_tx_power_ctl_setup there are some extra radio ops: radio_read(0x08bf) -> 0x0001 radio_write(0x08bf) <- 0x0001 radio_write(0x0159) <- 0x0011 On N-PHY we write 0x11 to TSSI regs, so it's probably sth similar. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
* b43: HT-PHY: finish calculating values for idle TSSIRafał Miłecki2013-04-23

* b43: HT-PHY: tables: don't duplicate core-generic regsRafał Miłecki2013-04-23
| | | | | | | Now when we know many radio regs at 0x000 are core-generic, I've noticed we duplicate some values in the tables. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
* b43: HT-PHY: rename defines addressing cores on the 2059 radioRafał Miłecki2013-04-23
| | | | | | | | | After comparing writes to registers at 0x000, 0x400 and 0x800 it seems there are many very similar writes. So 0x000 offset is not for accessing something totally different, but probably just the first out of three cores. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>

| | | | | | | | | | | | | | | | | | | | Drivers that don't use chanctxes cannot perform VHT association because they still use a "backward compatibility" pair of {ieee80211_channel, nl80211_channel_type} in ieee80211_conf and ieee80211_local.

* | b43: HT-PHY: implement stopping sample tone playbackRafał Miłecki2013-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It was another sequence I recognized in HT-PHY dump: phy_read(0x00c7) -> 0x0001 phy_read(0x00c3) -> 0x0000 phy_write(0x00c3) <- 0x0002 phy_read(0x00c3) -> 0x0000 phy_write(0x00c3) <- 0x0000 The difference to N-PHY is that it writes to 6 tables instead of a one (after above).

* | b43: HT-PHY: implement controlling TX power controlRafał Miłecki2013-03-13
| | | | | | | | | | | | | | | | | | Don't enable it until we have (almost?) whole TX power management figured out. It's similar to the N-PHY, the difference is that we call a "fix" *before* disabling power control. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | It was just another similar-to-N-PHY and easy-to-track routine: write32 0xb0601408 <- 0x00002057 phy_read(0x0001) -> 0x0000 phy_write(0x0001) <- 0x4000 phy_write(0x0001) <- 0x0000 write32 0xb0601408 <- 0x00002055 (b43_phy_ht_force_rf_sequence was moved up unmodified) Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W.

* | b43: HT-PHY: implement spurious tone avoidanceRafał Miłecki2013-03-13
| | | | | | | | | | | | | | | | | | On N-PHY it's also done after TX power fix, so it was easy to spot. Unfortunately the MMIO logs I have from ndsiwrapper include channels 1-12 only, so enabling code for 13 and 14 is just a N-PHY-based guess.

* | b43: HT-PHY: move TX fix to the separated functionRafał Miłecki2013-03-13
| | | | | | | | | | | | | | | | | | On N-PHY after B43_PHY_B_TEST operation there is a call to TX power fix function which iterates over available cores. It matches our HT-PHY code which means it's probably also some TX fix. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | b43: HT-PHY: rename AFE definesRafał Miłecki2013-03-13
| | | | | | | | | | | | | | | | | | | | It you take a look at N-PHY analog switch function it touches every core on the chipset. It seems HT-PHY does they same, it just has 3 cores instead of 2 (which make sense since BCM4331 is 3x3). Rename AFE defines to include core id.

* | b43: HT-PHY: make it BCMA-onlyRafał Miłecki2013-03-06
|/ | | | | | | | | | HT-PHY was found only on BCM4331 which is a BCMA-based chipset. This is reallly unlikely we will ever see HT-PHY on SSB thus make the whole code BCMA specific. This will allow us to call various BCMA-specific functions directly (without extra checks). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
