Update channel initialization to add the corresponding channels for this chip.

AFAIK the RF3052 needs the same initialization as for RF3020, RF3021, RF3022, etc extended with the correct values for 5GHz band. So, NAK for this patch. Also, please keep in mind that for proper RT3572 support more needs to be done, also in the register, BPP, and RFCSR initializations. > --- > drivers/net/wireless/rt2x00/rt2800lib.c | 9 +++++---- > 1 files changed, 5 insertions(+), 4 deletions(-) > > diff --git a/drivers/net/wireless/rt2x00/rt2800lib.c b/drivers/net/wireless/rt2x00/rt2800lib.c > index e7a61a3..0d6f715 100644 > --- a/drivers/net/wireless/rt2x00/rt2800lib.c > +++ b/drivers/net/wireless/rt2x00/rt2800lib.c > @@ -2223,7 +2223,7 @@ EXPORT_SYMBOL_GPL(rt2800_init_eeprom); > > /* > * RF value list for rt28x0 > - * Supports: 2.4 GHz (all) & 5.2 GHz (RF2850 & RF2750) > + * Supports: 2.4 GHz (all) & 5.2 GHz (RF2850, RF2750 & RF3052) > */ > static const struct rf_channel rf_vals[] = { > { 1, 0x18402ecc, 0x184c0786, 0x1816b455, 0x1800510b }, > @@ -2355,11 +2355,12 @@ int rt2800_probe_hw_mode(struct rt2x00_dev *rt2x00dev) > spec->supported_rates = SUPPORT_RATE_CCK | SUPPORT_RATE_OFDM; > > if (rt2x00_rf(rt2x00dev, RF2820) || > - rt2x00_rf(rt2x00dev, RF2720) || > - rt2x00_rf(rt2x00dev, RF3052)) { > + rt2x00_rf(rt2x00dev, RF2720)) { > spec->num_channels = 14; > spec->channels = rf_vals; > - } else if (rt2x00_rf(rt2x00dev, RF2850) || rt2x00_rf(rt2x00dev, RF2750)) { > + } else if (rt2x00_rf(rt2x00dev, RF2850) || > + rt2x00_rf(rt2x00dev, RF2750) || > + rt2x00_rf(rt2x00dev, RF3052)) { > spec->supported_bands |= SUPPORT_BAND_5GHZ; > spec->num_channels = ARRAY_SIZE(rf_vals); > spec->channels = rf_vals; > -- > 1.6.6.1 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-wireless" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > ^ permalink raw reply [flat|nested] 4+ messages in thread

It could be that the initialization of RF3052 is incomplete, however that is not limited to the 5GHz feature, but for both bands. Note that the difference in initialization only exists for settings the antenna and channel which already detect if the initialization should be done on the 2.4 or 5 GHz band. So this argument shouldn't block this patch... Ivo ^ permalink raw reply [flat|nested] 4+ messages in thread

I just talked with Gertjan and I will be sending an updated patch in a few minutes.
