If so, the module will be 1173 called twl4030-madc. 1174 1175config TWL6030_GPADC 1176 tristate "TWL6030 GPADC (General Purpose A/D Converter) Support" 1177 depends on TWL4030_CORE 1178 default n 1179 help 1180 Say yes here if you want support for the TWL6030/TWL6032 General 1181 Purpose A/D Converter. This will add support for battery type 1182 detection, battery voltage and temperature measurement, die 1183 temperature measurement, system supply voltage, audio accessory, 1184 USB ID detection. 1185 1186 This driver can also be built as a module. If so, the module will be 1187 called twl6030-gpadc. 1188 1189config VF610_ADC 1190 tristate "Freescale vf610 ADC driver" 1191 depends on OF 1192 depends on HAS_IOMEM 1193 select IIO_BUFFER 1194 select IIO_TRIGGERED_BUFFER 1195 help 1196 Say yes here to support for Vybrid board analog-to-digital converter. 1197 Since the IP is used for i.MX6SLX, the driver also support i.MX6SLX. 1198 1199 This driver can also be built as a module. If so, the module will be 1200 called vf610_adc. 1201 1202config VIPERBOARD_ADC 1203 tristate "Viperboard ADC support" 1204 depends on MFD_VIPERBOARD && USB 1205 help 1206 Say yes here to access the ADC part of the Nano River 1207 Technologies Viperboard. 1208 1209 To compile this driver as a module, choose M here: the module will be 1210 called viperboard_adc. 1211 1212config XILINX_XADC 1213 tristate "Xilinx XADC driver" 1214 depends on HAS_IOMEM 1215 select IIO_BUFFER 1216 select IIO_TRIGGERED_BUFFER 1217 help 1218 Say yes here to have support for the Xilinx XADC. The driver does support 1219 both the ZYNQ interface to the XADC as well as the AXI-XADC interface. 1220 1221 The driver can also be build as a module. If so, the module will be called 1222 xilinx-xadc. 1223 1224endmenu 1225
