+
+ Prefix: 'kbatt'
+
+Authors:
+
+ Gerhard Engleder <eg@keba.com>
+ Petar Bojanic <boja@keba.com>
+
+Description
+-----------
+
+The KEBA battery monitoring controller is an IP core for FPGAs, which
+monitors the health of a coin cell battery. The coin cell battery is
+typically used to supply the RTC during power off to keep the current
+time. E.g., the CP500 FPGA includes this IP core to monitor the coin cell
+battery of PLCs and the corresponding cp500 driver creates an auxiliary
+device for the kbatt driver.
+
+This driver provides information about the coin cell battery health to
+user space. Actually the user space shall be informed that the coin cell
+battery is nearly empty and needs to be replaced.
+
+The coin cell battery must be tested actively to get to know if its nearly
+empty or not. Therefore, a load is put on the coin cell battery and the
+resulting voltage is evaluated. This evaluation is done by some hard wired
+analog logic, which compares the voltage to a defined limit. If the
+voltage is above the limit, then the coin cell battery is assumed to be
+ok. If the voltage is below the limit, then the coin cell battery is
+nearly empty (or broken, removed, ...) and shall be replaced by a new one.
+The KEBA battery monitoring controller allows to start the test of the
+coin cell battery and to get the result if the voltage is above or below
+the limit. The actual voltage is not available. Only the information if
+the voltage is below a limit is available.
+
+The test load, which is put on the coin cell battery for the health check,
+is similar to the load during power off. Therefore, the lifetime of the
+coin cell battery is reduced directly by the duration of each test. To
+limit the negative impact to the lifetime the test is limited to at most
+once every 10 seconds. The test load is put on the coin cell battery for
+100ms. Thus, in worst case the coin cell battery lifetime is reduced by
+1% of the uptime or 3.65 days per year. As the coin cell battery lasts
+multiple years, this lifetime reduction negligible.
+
+This driver only provides a single alarm attribute, which is raised when
+the coin cell battery is nearly empty.

+Description
+-----------
+
+The KEBA fan controller is an IP core for FPGAs, which monitors the health
+and controls the speed of a fan. The fan is typically used to cool the CPU
+and the whole device. E.g., the CP500 FPGA includes this IP core to monitor
+and control the fan of PLCs and the corresponding cp500 driver creates an
+auxiliary device for the kfan driver.
+
+This driver provides information about the fan health to user space.
+The user space shall be informed if the fan is removed or blocked.
+Additionally, the speed in RPM is reported for fans with tacho signal.
+
+For fan control PWM is supported. For PWM 255 equals 100%. None-regulable
+fans can be turned on with PWM 255 and turned off with PWM 0.

+The MPM82504 is a quad 25A, scalable, fully integrated power module with a PMBus
+interface. The device offers a complete power solution that achieves up to 25A
+per output channel. The MPM82504 has four output channels that can be paralleled
+to provide 50A, 75A, or 100A of output current for flexible configurations.
+The device can also operate in parallel with the MPM3695-100 and additional
