cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37Z

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig Signed-off-by: Luis Chamberlain [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig

brcmfmac: Fix access point mode

Since commit 1204aa17f3b4 ("brcmfmac: set WIPHY_FLAG_HAVE_AP_SME flag") the Raspberry Pi 3 A+ (BCM43455) isn't able to operate in AP mode with hostapd (device_ap_sme=1 use_monitor=0): brcmfmac: brcmf_cfg80211_stop_ap: setting AP mode failed -52 So add the missing mgmt_stypes for AP mode to fix this.

brcmfmac: fix roamoff=1 modparam

2018-12-20T06:47:53Z

When the update_connect_param callback is set, nl80211 expects the flag WIPHY_FLAG_SUPPORTS_FW_ROAM to be set as well. However, this flag is only set when modparam roamoff=0, while the callback is set unconditionally. Since commit 7f9a3e150ec7 this causes a warning in wiphy_register, which breaks brcmfmac. Disable the update_connect_param callback when roamoff=0 to fix this.

When CONFIG_NO_AUTO_INLINE is set, we get a false-postive warning for the brcmf_fw_request_nvram_done() function, after gcc figures out that brcmf_fw_nvram_from_efi() might not set the 'data_len' variable, but fails to notice that it always returns NULL: drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c: In function 'brcmf_fw_request_nvram_done': drivers/net/wireless/broadcom/brcm80211/brcmfmac/firmware.c:560:11: error: 'data_len' may be used uninitialized in this function [-Werror=maybe-uninitialized] Mark it 'inline' to force gcc to understand this.

brcmfmac: disable command decode in sdio_aos

2018-12-13T14:57:27Z

AOS is a part of the SDIOD core that becomes active when the rest of SDIOD is sleeping to keep SDIO bus alive responding to reduced set of commands. Transaction between AOS and SDIOD is not protected, and if cmd 52 is received in AOS and in the middle of response state changed from AOS to SDIOD, response is corrupted and it causes to SDIO Host controller to hang.

brcmfmac: update 43012 F2 watermark setting to fix DMA Error during UDP RX Traffic

2018-12-13T14:57:22Z

The number of words that the read FIFO has to contain except the end of frame before sends data back to the host. Max watermark = (512B - 2* (BurstLength))/4 = (512 - 128)/4 = 384/4 = 0x60 so if burst length (i.e. BurstLength = 64) is increased, watermark has to be reduced. This is the optimal setting for this chip. Reviewed-by: Arend van Spriel Signed-off-by: Naveen Gupta Signed-off-by: Chi-Hsien Lin Signed-off-by: Kalle Valo

Allow GCI core enumuration with below changes: - Allow GCI to be added to core list even when it doesn't have a wrapper. - Allow 8K address space size. - Don't overwrite the address value when an additional size descriptor is in place.
