This will force the DCON 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 148 * state machine to reset to a (sane) initial state. Mitch Bradley 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 149 * did some testing and discovered that holding for 16 SMB_CLK cycles 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 150 * worked a lot more reliably, so that's what we do here. 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 151 * 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 152 * According to the cs5536 spec, to set GPIO14 to SMB_CLK we must 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 153 * simultaneously set AUX1 IN/OUT to GPIO14; ditto for SMB_DATA and 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 154 * GPIO15. 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 155 */ 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 156 cs5535_gpio_set(OLPC_GPIO_SMB_CLK, GPIO_OUTPUT_VAL); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 @157 cs5535_gpio_set(OLPC_GPIO_SMB_DATA, GPIO_OUTPUT_VAL); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 158 cs5535_gpio_set(OLPC_GPIO_SMB_CLK, GPIO_OUTPUT_ENABLE); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 159 cs5535_gpio_set(OLPC_GPIO_SMB_DATA, GPIO_OUTPUT_ENABLE); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 @160 cs5535_gpio_clear(OLPC_GPIO_SMB_CLK, GPIO_OUTPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 161 cs5535_gpio_clear(OLPC_GPIO_SMB_DATA, GPIO_OUTPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 162 cs5535_gpio_clear(OLPC_GPIO_SMB_CLK, GPIO_OUTPUT_AUX2); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 163 cs5535_gpio_clear(OLPC_GPIO_SMB_DATA, GPIO_OUTPUT_AUX2); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 @164 cs5535_gpio_clear(OLPC_GPIO_SMB_CLK, GPIO_INPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 @165 cs5535_gpio_clear(OLPC_GPIO_SMB_DATA, GPIO_INPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 166 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 167 for (x = 0; x < 16; x++) { 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 168 udelay(5); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 169 cs5535_gpio_clear(OLPC_GPIO_SMB_CLK, GPIO_OUTPUT_VAL); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 170 udelay(5); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 @171 cs5535_gpio_set(OLPC_GPIO_SMB_CLK, GPIO_OUTPUT_VAL); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 172 } 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 173 udelay(5); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 174 cs5535_gpio_set(OLPC_GPIO_SMB_CLK, GPIO_OUTPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 175 cs5535_gpio_set(OLPC_GPIO_SMB_DATA, GPIO_OUTPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 176 cs5535_gpio_set(OLPC_GPIO_SMB_CLK, GPIO_INPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 177 cs5535_gpio_set(OLPC_GPIO_SMB_DATA, GPIO_INPUT_AUX1); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 178 } 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 179 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 180 static void dcon_set_dconload_1(int val) 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 181 { 2159fb3729293c Nishad Kamdar 2018-11-07 182 gpiod_set_value(gpios[OLPC_DCON_LOAD], val); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 183 } 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 184 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 185 static int dcon_read_status_xo_1(u8 *status) 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 186 { 2159fb3729293c Nishad Kamdar 2018-11-07 187 *status = gpiod_get_value(gpios[OLPC_DCON_STAT0]); 2159fb3729293c Nishad Kamdar 2018-11-07 188 *status |= gpiod_get_value(gpios[OLPC_DCON_STAT1]) << 1; 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 189 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 190 /* Clear the negative edge status for GPIO7 */ 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 @191 cs5535_gpio_set(OLPC_GPIO_DCON_IRQ, GPIO_NEGATIVE_EDGE_STS); 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 192 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 193 return 0; 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 194 } 53c43c5ca13328 Greg Kroah-Hartman 2016-04-04 195 :::::: The code at line 191 was first introduced by commit :::::: 53c43c5ca13328ac8f415aa2251791b441a12b51 Revert "Staging: olpc_dcon: Remove obsolete driver" :::::: TO: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> :::::: CC: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- 0-DAY kernel test infrastructure Open Source Technology Center https://lists.01.org/pipermail/kbuild-all Intel Corporation
