The device need to receive a skb with necessary space for the ICV. So, the driver adds this space before to send the frame. Currently, once the frame is sent, the driver restore the original content of the skb. However, this step is useless. Mac80211 don't do it when software encryption is enabled. Once we have removed this step, it appears that it is no more necessary to keep hw_key in tx_priv. Then, it is possible to simplify a bunch of code in the Tx path. Signed-off-by:

When MFP is enabled, the multicast management frames are not protected, in fact. Instead, but they should include an IE containing the MMIC of the frames (i.e. a cryptographic signature). Until now, the driver didn't correctly detect this kind of frames (they are not marked protected but they are associated to a key) and didn't ask to the device to encrypt them. In add, the device is not able to generate the IE itself. Mac80211 has to generate the IE and let the device compute the MMIC. Signed-off-by:

The protection of the management frames is mainly done by mac80211. However, frames for the management of the BlockAck sessions are directly sent by the device. These frames have to be protected if MFP is in use. So the driver has to pass the MFP configuration to the device. Until now, the driver directly read the RSN IE of the BSS. However, it didn't work when the BSS was MFP capable (ieee80211w=1) and the local device has disabled MFP (ieee80211w=0). This patch read the MFP information directly from the struct ieee80211_sta. This information take into account the MFP negotiated during the association. In addition, the code is far simpler. Signed-off-by:

Until now, hif_map_link() get as argument the raw value for map_link_flags when map_link_flags is defined as a bitfield. It was error prone. Now hif_map_link() takes explicit value for every flags of the struct map_link_flags. Signed-off-by:

The protection of the management frames is mainly done by mac80211. However, frames for the management of the BlockAck sessions are directly sent by the device. These frames have to be protected if MFP is in use. So the driver has to pass the MFP configuration to the device. Until now, the BlockAck management frames were completely unprotected whatever the status of the MFP negotiation. So, some devices dropped these frames. The device has two knobs to control the MFP. One global and one per station. Normally, the driver should always enable global MFP. Then it should enable MFP on every station with which MFP was successfully negotiated. Unfortunately, the older firmwares only provide the global control. So, this patch enable global MFP as it is exposed in the beacon. Then it marks every station with which the MFP is effective. Thus, the support for the old firmwares is not so bad. It may only encounter some difficulties to negotiate BA sessions when the local device (the AP) is MFP capable (ieee80211w=1) but the station is not. The only solution for this case is to upgrade the firmware. Signed-off-by:

Both irqnum and irqarray properties reflect the same thing: the number of bits and bytes for interrupts at this chipset. E. g.: irqnum = 8 x irqarray This can be seen by the way pending interrupts are handled: /* During probe time */ pmic->irqs = devm_kzalloc(dev, pmic->irqnum * sizeof(int), GFP_KERNEL); /* While handling IRQs */ for (i = 0; i < pmic->irqarray; i++) { pending = hi6421_spmi_pmic_read(pmic, (i + pmic->irq_addr)); pending &= 0xff; for_each_set_bit(offset, &pending, 8) generic_handle_irq(pmic->irqs[offset + i * 8]); } Going further, there are some logic at the driver which assumes that irqarray is 2: /* solve powerkey order */ if ((i == HISI_IRQ_KEY_NUM) && ((pending & HISI_IRQ_KEY_VALUE) == HISI_IRQ_KEY_VALUE)) { generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_DOWN]); generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_UP]); pending &= (~HISI_IRQ_KEY_VALUE); } As HISI_IRQ_KEY_DOWN and HISI_IRQ_KEY_UP are fixed values and don't depend on irqnum/irqarray. The IRQ addr and mask addr seem to be also fixed, based on some comments at the OF parsing code. So, get rid of them too, removing the of parsing function completely. Signed-off-by: -

Both the SPMI controller and the SPMI PMIC driver depends on the SPMI bus support. The dependency for the regulator is also wrong: it should depends on the SPMI version of the HiSilicon 6421, and not on the normal one. Signed-off-by:

Using dev_dbg() is not too nice, as, instead of printing the name of the regulator, it prints "regulator.<number>", making harder to associate what is happening with each ldo line. So, add a debug-specific macro, which will print the rdev's name, just like the regulator core. Signed-off-by:
