Signed-off-by: Bitterblue Smith --- v7: - No change. v6: - Update copyright year. - Remove some unused includes. - Make all functions use the prefix "rtl92du". v5: - No change. v4: - Fix fw.h and led.h header guards. - Add empty lines. - Delete globalmutex_for_fwdownload and simplify rtl92d_download_fw. It can't run in parallel because mutex_for_hw_init in rtl92du_hw_init protects the entire function. v3: - No change. v2: - Patch is new in v2, split from patch 3/3 in v1. --- .../wireless/realtek/rtlwifi/rtl8192du/fw.c | 63 +++++++++++++++++++ .../wireless/realtek/rtlwifi/rtl8192du/fw.h | 9 +++ .../wireless/realtek/rtlwifi/rtl8192du/led.c | 10 +++ .../wireless/realtek/rtlwifi/rtl8192du/led.h | 9 +++ 4 files changed, 91 insertions(+) create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.c create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.h create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.c create mode 100644 drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.h diff --git a/drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.c b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.c new file mode 100644 index 000000000000..f74e4e84fe39 --- /dev/null +++ b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.c @@ -0,0 +1,63 @@ +// SPDX-License-Identifier: GPL-2.0 +/* Copyright(c) 2024 Realtek Corporation.*/ + +#include "../wifi.h" +#include "../rtl8192d/reg.h" +#include "../rtl8192d/def.h" +#include "../rtl8192d/fw_common.h" +#include "fw.h" + +int rtl92du_download_fw(struct ieee80211_hw *hw) +{ + struct rtl_priv *rtlpriv = rtl_priv(hw); + struct rtl_hal *rtlhal = rtl_hal(rtlpriv); + enum version_8192d version = rtlhal->version; + u8 *pfwheader; + u8 *pfwdata; + u32 fwsize; + int err; + + if (rtlpriv->max_fw_size == 0 || !rtlhal->pfirmware) + return 1; + + fwsize = rtlhal->fwsize; + pfwheader = rtlhal->pfirmware; + pfwdata = rtlhal->pfirmware; + rtlhal->fw_version = (u16)GET_FIRMWARE_HDR_VERSION(pfwheader); + rtlhal->fw_subversion = (u16)GET_FIRMWARE_HDR_SUB_VER(pfwheader); + + rtl_dbg(rtlpriv, COMP_INIT, DBG_LOUD, + "FirmwareVersion(%d), FirmwareSubVersion(%d), Signature(%#x)\n", + rtlhal->fw_version, rtlhal->fw_subversion, + GET_FIRMWARE_HDR_SIGNATURE(pfwheader)); + + if (IS_FW_HEADER_EXIST(pfwheader)) { + rtl_dbg(rtlpriv, COMP_INIT, DBG_LOUD, + "Shift 32 bytes for FW header!!\n"); + pfwdata = pfwdata + 32; + fwsize = fwsize - 32; + } + + if (rtl92d_is_fw_downloaded(rtlpriv)) + goto exit; + + /* If 8051 is running in RAM code, driver should + * inform Fw to reset by itself, or it will cause + * download Fw fail. + */ + if (rtl_read_byte(rtlpriv, REG_MCUFWDL) & BIT(7)) { + rtl92d_firmware_selfreset(hw); + rtl_write_byte(rtlpriv, REG_MCUFWDL, 0x00); + } + + rtl92d_enable_fw_download(hw, true); + rtl92d_write_fw(hw, version, pfwdata, fwsize); + rtl92d_enable_fw_download(hw, false); + + err = rtl92d_fw_free_to_go(hw); + if (err) + pr_err("fw is not ready to run!\n"); +exit: + err = rtl92d_fw_init(hw); + return err; +} diff --git a/drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.h b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.h new file mode 100644 index 000000000000..7904bfbda4ba --- /dev/null +++ b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/fw.h @@ -0,0 +1,9 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +/* Copyright(c) 2024 Realtek Corporation.*/ + +#ifndef __RTL92DU_FW_H__ +#define __RTL92DU_FW_H__ + +int rtl92du_download_fw(struct ieee80211_hw *hw); + +#endif diff --git a/drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.c b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.c new file mode 100644 index 000000000000..6c12dfbd6367 --- /dev/null +++ b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.c @@ -0,0 +1,10 @@ +// SPDX-License-Identifier: GPL-2.0 +/* Copyright(c) 2024 Realtek Corporation.*/ + +#include "../wifi.h" +#include "led.h" + +void rtl92du_led_control(struct ieee80211_hw *hw, enum led_ctl_mode ledaction) +{ + /* The hardware has control. */ +} diff --git a/drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.h b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.h new file mode 100644 index 000000000000..d7ebc8afcc7b --- /dev/null +++ b/drivers/net/wireless/realtek/rtlwifi/rtl8192du/led.h @@ -0,0 +1,9 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +/* Copyright(c) 2024 Realtek Corporation.*/ + +#ifndef __RTL92DU_LED_H__ +#define __RTL92DU_LED_H__ + +void rtl92du_led_control(struct ieee80211_hw *hw, enum led_ctl_mode ledaction); + +#endif
