2020-05-12mt76: mt7615: rework IRQ handling to prepare for MSI supportFelix Fietkau1-1/+2
With MSI interrupts, IRQs must not be enabled from within the IRQ handler, because that can lead to lost events. Defer IRQ processing to a tasklet, which is also responsible for enabling IRQs (to avoid race conditions against the handler) Co-developed-by: Soul Huang <Soul.Huang@mediatek.com> Acked-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Soul Huang <soul.huang@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: Introduce mt76_mcu data structureLorenzo Bianconi1-3/+0
Introduce mt76_mcu data structure to contain common fields between mt76u_mcu and mt76e_mcu. Initialize mcu common fields in mt76_alloc_device(). Rely on mt76_mcu in mt76_mcu_rx_event and in mt76_mcu_get_response in order to reuse them in usb code Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-09-05mt76: switch to SPDX tag instead of verbose boilerplate textRyder Lee1-12/+1
No functional change intended. Add SPDX identifiers to all remaining files in /mt76. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-09-05mt76: introduce mt76_mmio_read_copy routineLorenzo Bianconi1-3/+10
Add mt76_mmio_read_copy routine and the related function pointer in mt76_bus_ops data structure. mt76_mmio_read_copy will be used to add BIP_CMAC_128 cipher hw support to mt7615 driver Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-09-05mt76: round up length on mt76_wr_copyFelix Fietkau1-1/+1
When beacon length is not a multiple of 4, the beacon could be sent with the last 1-3 bytes corrupted. The skb data is guaranteed to have enough room for reading beyond the end, because it is always followed by skb_shared_info, so rounding up is safe. All other callers of mt76_wr_copy have multiple-of-4 length already. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76: use readl/writel instead of ioread32/iowrite32Felix Fietkau1-2/+2
Switching to readl/writel is faster because it gets rid of an unnecessary wrapper with extra checks. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76: mmio: move mt76x02_set_irq_mask in mt76 moduleLorenzo Bianconi1-0/+13
Move mt76x02_set_irq_mask in mt76 module in order to be reused adding support for mt7603 driver and remove duplicated code Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-10-13mt76: allow to identify busStanislaw Gruszka1-0/+1
Add helpers to identify bus type. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-10-01mt76: mmio: add implementation of wr_rp and rd_rpLorenzo Bianconi1-0/+26
Introduce mmio implementation of mt76_mmio_rd_rp and mt76_mmio_wr_rp and remove mt76x2 duplicated code. mt76_mmio_{wr,rd}_rp allows to reuse mt76x0 init code adding mt76x0e support Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-10-01mt76: move mt76x02_set_irq_mask in mt76x02_mmio.cLorenzo Bianconi1-0/+1
Move mt76x02_set_irq_mask, mt76x02_irq_enable and mt76x02_irq_disable in mt76x02-lib module in order to be reused by mt76x0 driver. Moreover move irq_lock and irqmask in mt76_mmio data structure Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2018-09-19mt76: introduce mmio data structure in mt76_devLorenzo Bianconi1-0/+4
Introduce mt76_mmio data structure in mt76_dev and move mt76x2_mcu in mt76_mmio. This is a preliminary patch to unify mcu code between mt76x02{e,u} drivers Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
