+
+
+Implementation details
+======================
+
+For the interested, here's the code flow which happens inside the kernel
+when you use the /dev interface to I2C:
+
+1* Your program opens /dev/i2c-N and calls ioctl() on it, as described in
+section "C example" above.
+
+2* These open() and ioctl() calls are handled by the i2c-dev kernel
+driver: see i2c-dev.c:i2cdev_open() and i2c-dev.c:i2cdev_ioctl(),
+respectively. You can think of i2c-dev as a generic I2C chip driver
+that can be programmed from user-space.
+
+3* Some ioctl() calls are for administrative tasks and are handled by
+i2c-dev directly. Examples include I2C_SLAVE (set the address of the
+device you want to access) and I2C_PEC (enable or disable SMBus error
+checking on future transactions.)
+
+4* Other ioctl() calls are converted to in-kernel function calls by
+i2c-dev. Examples include I2C_FUNCS, which queries the I2C adapter
+functionality using i2c.h:i2c_get_functionality(), and I2C_SMBUS, which
+performs an SMBus transaction using i2c-core.c:i2c_smbus_xfer().
+
+The i2c-dev driver is responsible for checking all the parameters that
+come from user-space for validity. After this point, there is no
+difference between these calls that came from user-space through i2c-dev
+and calls that would have been performed by kernel I2C chip drivers
+directly. This means that I2C bus drivers don't need to implement
+anything special to support access from user-space.
+
+5* These i2c-core.c/i2c.h functions are wrappers to the actual
+implementation of your I2C bus driver. Each adapter must declare
+callback functions implementing these standard calls.
+i2c.h:i2c_get_functionality() calls i2c_adapter.algo->functionality(),
+while i2c-core.c:i2c_smbus_xfer() calls either
+adapter.algo->smbus_xfer() if it is implemented, or if not,
+i2c-core.c:i2c_smbus_xfer_emulated() which in turn calls
+i2c_adapter.algo->master_xfer().
+
+After your I2C bus driver has processed these requests, execution runs
+up the call chain, with almost no processing done, except by i2c-dev to
+package the returned data, if any, in suitable format for the ioctl.

+static struct regulator_consumer_supply regulator2_consumers[] = {
+{
+ .dev = &platform_consumerA_device.dev,
+ .supply = "Vcc",
+},};
This maps Regulator-1 to the 'Vcc' supply for Consumer B and maps Regulator-2
to the 'Vcc' supply for Consumer A.
-
-2. Regulator supply configuration.
-==================================
-Consider the following machine (again) :-
-
- Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
- |
- +-> [Consumer B @ 3.3V]
+Constraints can now be registered by defining a struct regulator_init_data
+for each regulator power domain. This structure also maps the consumers
+to their supply regulator :-
+
+static struct regulator_init_data regulator1_data = {
+ .constraints = {
+ .min_uV = 3300000,

+ .valid_modes_mask = REGULATOR_MODE_NORMAL,
+ },
+ .num_consumer_supplies = ARRAY_SIZE(regulator1_consumers),
+ .consumer_supplies = regulator1_consumers,
+};
Regulator-1 supplies power to Regulator-2. This relationship must be registered
with the core so that Regulator-1 is also enabled when Consumer A enables it's
-supply (Regulator-2).
-
-This relationship can be register with the core via :-
-
-int regulator_set_supply(const char *regulator, const char *regulator_supply);
-
-In this example we would use the following code :-
-
-regulator_set_supply("Regulator-2", "Regulator-1");
-
-Relationships can be queried by calling :-
-
-const char *regulator_get_supply(const char *regulator);
-
-
-3. Power Domain constraint setting.
-===================================
-Each power domain within a system has physical constraints on voltage and
-current. This must be defined in software so that the power domain is always
-operated within specifications.
-
-Consider the following machine (again) :-
-
- Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
- |
- +-> [Consumer B @ 3.3V]
-
-This gives us two regulators and two power domains:
-
- Domain 1: Regulator-2, Consumer B.
- Domain 2: Consumer A.

-struct regulation_constraints domain_1 = {

+static struct regulator_init_data regulator2_data = {
+ .supply_regulator_dev = &platform_regulator1_device.dev,
+ .constraints = {
+ .min_uV = 1800000,

- .max_uV = 2000000,

- *
- * Note the following:
- *
- * 1. When there is no byte available to read from the SCSI bus, or
- * when a byte cannot yet bet written to the SCSI bus, a bus
- * error occurs when reading or writing the pseudo DMA data
- * register (hades_psdm_reg). We have to catch this bus error
- * and try again to read or write the byte. If after several tries
- * we still get a bus error, the interrupt handler is left. When
- * the byte can be read or written, the interrupt handler is
- * called again.
- *
- * 2. The SCSI interrupt must be disabled in this interrupt handler.
- *
- * 3. If we set the EOP signal, the SCSI controller still expects one
- * byte to be read or written. Therefore the last byte is transferred
- * separately, after setting the EOP signal.
- *
- * 4. When this function is left, the address pointer (start_addr) is
- * converted to a physical address. Because it points one byte
- * further than the last transferred byte, it can point outside the
- * current page. If virt_to_phys() is called with this address we
- * might get an access error. Therefore virt_to_phys() is called with
- * start_addr - 1 if the count has reached zero. The result is
- * increased with one.
