* b43: HT-PHY: do some extra TSSI setup after configuring TXRafał Miłecki2013-04-231-0/+13
| | | | | | | | | | 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: tables: don't duplicate core-generic regsRafał Miłecki2013-04-231-21/+14
| | | | | | | 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 Miłecki2013-04-231-11/+11
| | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | 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.

* | b43: HT-PHY: implement spurious tone avoidanceRafał Miłecki2013-03-131-0/+20
| | | | | | | | | | | | | | | | | | 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 Miłecki2013-03-131-18/+28
| | | | | | | | | | | | | | | | | | 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 Miłecki2013-03-131-19/+19
| | | | | | | | | | | | | | | | | | | | 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 Miłecki2013-03-061-0/+5
|/ | | | | | | | | | 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>
