2019-02-26mt76usb: remove usb_mcu.cStanislaw Gruszka1-34/+0
Don't need separate file just for kmalloc/kfree. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-26mt76usb: use synchronous msg for mcu command responsesStanislaw Gruszka1-27/+4
Use usb_bulk_msg for reading MCU command responses. This simplify code a lot. Together with 97a3005759c ("mt76usb: allow mt76u_bulk_msg be used for reads") it also fix possible problems with rx data buffers not being aligned and contained within single page. After doing page_frag_alloc(1024) consecutive page_frag_alloc(PAGE_SIZE) will alloc PAGE_SIZE buffer at PAGE_SIZE - 1024 offset.

2019-02-18mt76: usb: do not use sg buffers for mcu messagesLorenzo Bianconi1-3/+2
Do not use scatter-gather buffers for mcu commands. Introduce mt76u_buf_alloc and mt76u_buf_alloc_sg routines. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: usb: fix possible NULL pointer dereference in mt76u_mcu_deinitLorenzo Bianconi1-3/+5
Fix possible NULL pointer dereference in mt76u_mcu_deinit routine that can occur if initialization path fails before calling mt76u_mcu_init_rx Fixes: ee676cd5017c ("mt76: add driver code for MT76x2u based devices") Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-09-19mt76: usb: move mt76x02 mcu code in mt76x02-usb moduleLorenzo Bianconi1-335/+0
Introduce mt76x02_usb_mcu.c in order to contain mt76x02u mcu related code. Add mt76x02-usb module as a container for mt76x02 usb code. This is a preliminary patch to move MT_TXD_INFO, MT_MCU_MSG and MT_RX_FCE_INFO defs in mt76x02-lib module since other chipsets (e.g. mt7603) use different dma definitions Acked-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-09-19mt76: usb: use common helpers for mcu_alloc_msg()/mcu_send_msg()Lorenzo Bianconi1-12/+14
Use mcu common helpers instead of usb specific routines. Add static qualifier to the following functions: - mt76u_mcu_msg_alloc - __mt76u_mcu_send_msg - mt76u_mcu_send_msg - mt76u_mcu_wr_rp - mt76u_mcu_rd_rp - mt76u_wr_rp - mt76u_rd_rp This is a preliminary patch to move mt76x02 usb mcu code in mt76x02-usb module Acked-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-09-19mt76: add rd_rp and wr_rp to bus_ops/mcu_opsStanislaw Gruszka1-0/+2
Add callbacks for reading and writing reg pairs tables. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-09-19mt76: add usb implementation of {wr,rd}_rpStanislaw Gruszka1-0/+79
Add USB implementation for read and write reg pair routines. The actual implementation can use mcu related routines according to MCU state Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-09-19mt76: add mt76_mcu_ops data structure for mcu related pointersLorenzo Bianconi1-0/+10

2018-09-04mt76: add multiple regs read support to usb_mcu layerLorenzo Bianconi1-1/+38
Introduce multiple regs read support to mcu layer in mt76-usb module. Multiple regs read will be reused by mt76x0 driver in usb mcu layer unification between mt76x0 and mt76x2u drivers Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
