128 | * (see below) is not, the check is performed on such table | |
129 | * (a register is writeable if it belongs to one of the ranges | |
130 | * specified by wr_table). | |

76aad392 | 142 | * should not be read outside of a call from the driver |
bdc39644 | 143 | * (e.g., a clear on read interrupt status register). If this |

d2a5884a AS |

154 | * all the reads from the registers. Should only be provided for | |
bdc39644 LP |
155 | * devices whose read operation cannot be represented as a simple |
156 | * read operation on a bus such as SPI, I2C, etc. Most of the | |
157 | * devices do not need this. | |
d2a5884a AS |
158 | * @reg_write: Same as above for writing. |
159 | * @fast_io: Register IO is fast. Use a spinlock instead of a mutex | |
160 | * to perform locking. This field is ignored if custom lock/unlock | |
161 | * functions are used (see fields lock/unlock of struct regmap_config). | |
162 | * This field is a duplicate of a similar file in | |
163 | * 'struct regmap_bus' and serves exact same purpose. | |
164 | * Use it only for "no-bus" cases. | |
bd20eb54 | 165 | * @max_register: Optional, specifies the maximum valid register index. |
76aad392 DC |

167 | * valid ranges for write access. | |
168 | * @rd_table: As above, for read access. | |
169 | * @volatile_table: As above, for volatile registers. | |

6f306441 LPC |

175 | * @read_flag_mask: Mask to be set in the top byte of the register when doing | |
176 | * a read. | |
177 | * @write_flag_mask: Mask to be set in the top byte of the register when doing | |
178 | * a write. If both read_flag_mask and write_flag_mask are | |
179 | * empty the regmap_bus default masks are used. | |
2e33caf1 AJ |
180 | * @use_single_rw: If set, converts the bulk read and write operations into |
181 | * a series of single read and write operations. This is useful | |
182 | * for device that does not support bulk read and write. | |
e894c3f4 OAO |
183 | * @can_multi_write: If set, the device supports the multi write mode of bulk |
184 | * write operations, if clear multi write requests will be | |
185 | * split into individual write operations | |
9fabe24e DP |
186 | * |
187 | * @cache_type: The actual cache type. | |
